33.1b), CT scan axial images (c), and bone scintigraphy (d). Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. This could be an osteoblastic metastasis or an osteolytic metastasis that responded to chemotherapy. When considering congenital causes of sclerotic lesions, benign causes such as bone islands or osteopoikilosis usually have a fairly typical appearance and are hard to mistake. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Notice that in all three patients, the growth plates have not yet closed. Osteosarcoma, chondrosarcoma, and Ewing's sarcoma are the most common types of bone cancer. Stress fractures occur in normal (fatigue fractures) or metabolically weakened (insufficiency fractures) bones. Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. by Mulder JD et al Fibrous dysplasia, enchondromas, EG, Mets and myeloma, Hyperparathyroidism, Infection. Enchondromas aswell as low-grade chondrosarcomas are frequently encountered as coincidental findings in patients who have a MRI or bone scan for other reasons. An ill-defined border with a broad zone of transition is a sign of aggressive growth (1). Small zone of transitionA small zone of transition results in a sharp, well-defined border and is a sign of slow growth.A sclerotic border especially indicates poor biological activity. 2. In aggressive periostitis the periosteum does not have time to consolidate. AJR Am J Roentgenol. At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. This feature differentiates it from a juxtacortical tumor. However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. In this case, because of the increased uptake on bone scintigraphy, a follow-up MRI was recommended at 6 and 12 months. This image is of a 20 year old patient with a sclerotic expansile lesion in the clavicle. Here two other lesions in different patients that proved to be chondrosarcoma. -. This part corresponds to a zone of high SI on T2-WI with FS on the right. Metastases must be included in the differential diagnosis of any bone lesion, whether well-defined or ill-defined osteolytic or sclerotic in age > 40. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . Sclerosis can also be reactive, e.g. When considering Pagets disease, it is extremely helpful to note whether there is associated bony enlargement. Less dense on CT and more heterogeneous than bone islands. Arthritis Rheum., 42 (2012), pp. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. In general, they're slow-growing.. Infection is seen in all ages. Even though plain X-ray and CT would typically be used to follow a suspected bone island, MRI was chosen as the follow-up modality because the sacrum is an area not well seen on plain films due to overlying bowel gas and concern regarding radiation dose from multiple CT scans to the pelvis of a 30-year-old woman. Here, we showed that sBT values are higher in patients presenting 496 with bone loss . Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. Osteoblastic metastases (2) Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. 3, Increased uptake on bone scan associated with a solitary sclerotic lesion is atypical and therefore more worrisome, but largely unhelpful as there are many reports of bone islands having increased Tc-99 m hydroxydiphosphonate (HDP) uptake. (white arrows). This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). Fibrous dysplasia, Enchondroma, NOF and SBC are common bone lesions.They will not present with a periosteal reaction unless there is a fracture.If no fracture is present, these bone tumors can be excluded. Presentation: pain, mass, pathologic fracture. 14. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. A sclerotic border especially indicates poor biological activity. Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Authors Usually stress fractures are easy to recognize. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. In an older patient one should first consider an osteoblastic metastasis. Generic Differential Diagnosis of Sclerotic Bone Lesions. CT of Sclerotic Bone Lesions: Imaging Features Differentiating Tuberous Sclerosis Complex with Lymphangioleiomyomatosis from Sporadic Lymphangioleiomymatosis1. growth of osteohondroma in skeletally mature patients, irregular or indistinct surface of lesions, soft tissue mass with scattered or irregular calcifications. In 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. 2020;60(Suppl 1):1-16. A high grade chondrosarcoma must be considered in the differential diagnosis. Solitary sclerotic bone lesion. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. ADVERTISEMENT: Supporters see fewer/no ads. A mnemonicfor remembering the causes of diffuse bony sclerosis is: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Aggressive periosteal reaction There are no calcifications. Finally other clues need to be considered, such as a lesion's localization within the skeleton and within the bone, any periosteal reaction, cortical destruction, matrix calcifications, etc. MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. Diagnostic brain imaging tests can assess bone fractures, structural problems, blood vessel abnormalities, and changes in brain metabolism. Interventional Radiology). The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient. Radiographs are specific but suffer from low sensitivity 1. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. 6. 3. Differential diagnosis Complete envelopment may occur. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. Imaging: Prevalence of 3-5% in patients with hereditary multiple osteohondromas. Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. There is no calcification and lesions may be expansile. The cortical bone and bone marrow compartment are not involved. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. The radiograph shows typical bone infarcts in diaphysis and metaphysis of femur and tibia.. On MR imaging bone infarcts are characterized by irregulair serpentiginous margins with low signal intensity on both T1 and T2 WI and with intermediate to high fat signal in the center part. Sclerotic bone lesions as a potential imaging biomarker for the diagnosis of tuberous sclerosis complex Authors Susanne Brakemeier 1 , Lars Vogt 2 , Lisa C Adams 2 , Bianca Zukunft 3 , Gerd Diederichs 2 , Bernd Hamm 2 , Klemens Budde 3 , Kai-Uwe Eckardt 3 , Marcus R Makowski 2 4 Affiliations Here an illustration of the most common sclerotic bone tumors. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. Infections and eosinophilic granulomaInfections and eosinophilic granuloma are exceptional because they are benign lesions which can mimick a malignant bone tumor due to their aggressive biologic behavior. Spinal lesions are commonly spotted on imaging tests. Unable to process the form. Skeletal Radiol. Typical bone metastases are osteolytic (87.5%), with medullary origin (91.6%), and they cannot be distinguished from other osteolytic metastases on the basis of imaging criteria alone. Sclerotic metastases arise from . A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. Notice the numerous ill-defined osteoblastic metastases. Society of Skeletal Radiology- White Paper. Radiographs are specific but suffer from low sensitivity 1. found incidentally on the imaging studies. Confavreux C, Follet H, Mitton D, Pialat J, Clzardin P. Fracture Risk Evaluation of Bone Metastases: A Burning Issue. Many lesions can be located in both or move from the metaphysis to the diaphysis during growth. brae in keeping with diffuse bone infarcts. mutation, and both sclerotic and lytic bone lesions together for the first time. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts 2014;71(1):39. This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. Well, generally, it means that it is due to a fairly slow-growing process. One study, using a mean attenuation of 885 HU and a maximum attenuation of 1,060 HU as cut-off values, distinguished the higher density bone islands from lower density osteoblastic metastases with 95% sensitivity and 96% specificity. It is true that the usual appearance of skeletal metastases is that of focal lesions diffuse sclerosis occurs in only a small fraction of cases of skeletal metastases. Bker S, Adams L, Bender Y et al. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) Diffuse bony sclerosis (mnemonic). (2005) ISBN: 9780721602707 -. Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. The lesion shows increased uptake of the tracer in the bone scan (arrow in Fig. Here an example of a patient with a stress fracture of the distal fibula. How should one approach sclerotic bone disease? Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. Biopsy revealed dedifferentiated chondrosarcoma. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. J Korean Soc Radiol. (see diagnostic imaging pearls). 4. RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. 2 ed. 2. Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . 1989. The MR image shows that the lesion has lobulated contours and nodular enhancement. The sagittal T1WI and Gd-enhanced T1W-image with fatsat show a large tumor mass infiltrating a large portion of the distal femur and extending through the cortex into the soft tissues. If you can find evidence of subchondral collapse or the typical lucent/sclerotic appearance of the necrotic bone in the weight-bearing bone, then osteonecrosis becomes a much more likely diagnosis. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. Check for errors and try again. Classic ground glass appearance of the bone. Mineralization in osteoid tumors can be described as a trabecular ossification pattern in benign bone-forming lesions and as a cloud-like or ill-defined amorphous pattern in osteosarcomas. Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. In Section 2, we give the general technical route for classification, detection and segmentation of multiple-lesion.After that, in Section 3, the paper will review the recognition of multiple-lesion in six organ and tissue areas, including brain, eye, skin, breast, lung, and abdomen. This solitary, uniformly high-density lesion with neither edema in the surrounding bone marrow nor extension into the surrounding soft tissue most likely represents a giant bone island. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. It classically presents with nocturnal pain in young patients, painful scoliosis, and marked relief from NSAIDs (nonsteroidal anti-inflammatory drugs). Most cases of chronic osteomyelitis look pretty nonspecific. There is a metastasis, which presents as a subtle sclerotic lesion in the humerus metaphysis. Enchondroma is a fairly common benign cartilaginaous lesion which may present as an entirely lytic lesion without any calcification, as a dense calcified lesion or as a mixed leson with osteolysis and calcifications. Notice the lytic peripheral part with subtle calcifications. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. Mnemonic for multiple oseolytic lesions: FEEMHI: 4, Although usually stable in size, bone islands may increase or decrease in size or disappear. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. 5, In the cases with no known primary malignancy that are being followed with serial imaging, if the lesion increases in diameter by greater than 25% at 6 months or less, or greater than 50% at 12 months, open biopsy has been recommended by Brien et al. D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. Growth of osteochondroma in skeletally mature patient, Irregular or indistinct surface of lesions, focal lucent regions in interior of lesions, presence of soft tissue mass with scattered or irregular calcifications. These lesions were possibly misinterpreted as new when applying WHO criteria. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. Chang C, Garner H, Ahlawat S et al. Notice the homogeneous thickening of the cortical bone. Physical examination and past medical history were normal and noncontributory respectively. Differentiating between a diaphyseal and a metaphyseal location is not always possible. The mean and maximum attenuation were measured in Hounsfield units. For the unexpected bone lesions, the distinguishing anatomic features and a generalized imaging approach will be reviewed for four frequently encountered scenarios: chondroid lesions, sclerotic bone lesions, osteolytic lesions, and areas of focal marrow abnormality. (B) In another patient, a 21-year-old woman, note a radiolucent lesion with sclerotic border affecting the medial cortex of the distal femur ( arrows ). Abbreviations used: The most important determinators in the analysis of a potential bone tumor are: It is important to realize that the plain radiograph is the most useful examination for differentiating these lesions.CT and MRI are only helpful in selected cases. Fibrous dysplasia can be monostotic or polyostotic. There are two kinds of mineralization: Chondroid matrix DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. SWI:low signal intensity on the inverted magnitude and phase images 9. . However, a specific density range has not been specified for those terms 1. Metastases are the most common malignant bone tumors. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. A periosteal reaction with or without layering may be present. Skeletal Radiol. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. Osteosarcoma (2) It grows primarily into the surrounding soft tissues, but may also infiltrate into the bone marrow. Growth of osteochondromas at adult ages, which is characterized by a thick cartilaginous cap (high SI on T2WI) should raise the suspicion of progression to a peripheral chondrosarcoma. Home. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Moreover, questions such as the . (2007) ISBN:0781765188. Cancers (Basel). In some cases however the osteolytic nidus can be visible on the radiograph (figure). A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. It is most commonly located in the outer table of the neurocranium or in a paranasal sinus. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. 2018;10(6):156. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. Chrondroid tumors are more frequently encountered than bone infarcts. Uncommonly it can be difficult to differentiate a stress fracture from a bone tumor like an osteoid osteoma or from a pathologic fracture, that occurs at the site of a bone tumor. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. Here a patient with a broad-based osteochondroma. Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. In some locations, such as in the humerus or around the knee, almost all bone tumors may be found. by Clyde A. Helms Coronal T1W image shows lobulated margins and peripheral low SI due to the calcifications. Osteoma consists of densely compact bone. Both imaging modalities achieved only a moderate correlation with DEXA. Teaching Point: Metastasis is the most common malignant rib lesion. in Ewing's sarcoma or lymphoma. Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition The most common appearance is the mixed lytic-sclerotic. 2018;2018:1-5. The most reliable indicator in determining whether these lesions are benign or malignant is the zone of transition between the lesion and the adjacent normal bone (1). Notice the numerous predominantly osteoblastic metastases. Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . Here are links to other articles about bone tumors: Most bone tumors are osteolytic. 2021;13(22):5711. Lippincott Williams & Wilkins. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. MRI of the sacrum: axial T1-weighted (T1w; Fig. Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. Semin. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. Bone scintigraphy can be either negative or show limited uptake. Amsterdam: Elsevier, 1993. A 30-year-old woman underwent a CT of the pelvis for endometriosis and an incidental lesion was found in the sacrum. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). Amsterdam: Elsevier; 1993. Donald Resnick, Mark J. Kransdorf. Several genes have been discovered that, when disrupted, result in specific types . This proved to be a reactive calcification secondary to trauma.

Osteosclerotic Myeloma Variants. On the left three bone lesions with a narrow zone of transition. Adamantinoma in case of a sclerotic lesion with several lucencies of the tibia in a young patient. The zone of transition is the most reliable indicator in determining whether an osteolytic lesion is benign or malignant (1). Usually one bone is involved. Radiology. Radiographic features that should raise the suspicion of malignant transformation on plain radiographs or CT include: Here the reactive sclerosis is the most obvious finding on the X-ray. 1. This could very well be an enchondroma. Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. The lesion is predominantly calcified. Eosinophilic granuloma like osteomyelitis, can be a serious mimicker of malignancy (particularly Ewing sarcoma). Fundamentals of diagnostic radiology. 7A, and 7B ). The juxtacortical mass has a high SI and lobulated contours. CT Radiological hallmark: formation of a chondroid (cartilagenous) matrix, which presents as punctuated, stippled or popcorn-like calcifications. CT scan is usually very helpful in detecting the nidus and differentiating osteoid osteoma from other sclerotic lesions like osteoblastoma, osteomyelitis, arthritis, stress fracture and enostosis. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. 10. Sclerotic or blastic bone metastases can arise from a number of different primary malignancies including prostate carcinoma (most common), breast carcinoma (may be mixed), transitional cell carcinoma (TCC), carcinoid, medulloblastoma, neuroblastoma, mucinous adenocarcinoma of the gastrointestinal tract (e.g., colon carcinoma, gastric carcinoma), Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. In this case we see the pathognomonic triad of bone expansion, cortical thickening and trabecular bone thickening in the mixed lytic and sclerotic phase of Paget's disease of right hemipelvis. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. After an injury, different types of fluid can build up in a bone. 12. some benign entities in this region may mimic malignancy if analyzed using classical bone-tumor criteria, and proper patient management requires being familiar with these presentations. It can identify small or large tumors, multiple sclerosis (MS), encephalitis (brain inflammation), or meningitis (inflammation of the meninges that lie between the brain and the skull). Continue with the MR-images. AJR 1995;164:573-580, Online teaching by the Musculoskeletal Radiology academic section of the University of Washington, by Theodore Miller March 2008 Radiology, 246, 662-674, by Laura M. Fayad, Satomi Kawamoto, Ihab R. Kamel, David A. Bluemke, John Eng, Frank J. Frassica and Elliot K. Fishman. The benign type is seen in benign lesions such as benign tumors and following trauma. BallooningBallooning is a special type of cortical destruction.In ballooning the destruction of endosteal cortical bone and the addition of new bone on the outside occur at the same rate, resulting in expansion. See article: bone metastases. Multiple enchondromas are seen in Morbus Ollier. Fundamentals of Skeletal Radiology, second edition 1988;17(2):101-5.
