Enchondromas aswell as low-grade chondrosarcomas are frequently encountered as coincidental findings in patients who have a MRI or bone scan for other reasons. Adamantinoma in case of a sclerotic lesion with several lucencies of the tibia in a young patient. 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. Most bone tumors are solitary lesions. 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. Geode or subchondral cyst in the navicular bone, Geode or subchondral cyst in the tarsal bone, X-ray and MRI of a chondroblasoma in the tarsal bone, Chondromyxoid fibroma (CMF) in the calcaneus. Most of the time, sclerotic lesions are benign. Rib metastases may be osteolytic, sclerotic, or mixed. 2014;71(1):39. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). WSI digital slide: https://kikoxp.com/posts/4606. Here an example of a patient with a stress fracture of the distal fibula. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. 2021;216(4):1022-30. 14. Ulano A, Bredella M, Burke P et al. 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. Fibro-osseous lesion like fibrous dysplasia. Moreover, questions such as the . Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. Enhancement after i.v. This could be an osteoblastic metastasis or an osteolytic metastasis that responded to chemotherapy. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. 7, Behrang Amini, Susana Calle, Octavio Arevalo, Richard M. Westmark, and Kaye D. Westmark, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on 33 Incidental Solitary Sclerotic Bone Lesion, 27 Approach to the Solitary Vertebral Lesion on Magnetic Resonance Imaging, 28 Diffusely Abnormal Marrow Signal within the Vertebrae on MRI, Incidental Findings in Neuroimaging and Their Management, Radiology (incl. O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Infection with a multilayered periosteal reaction. Lippincott Williams & Wilkins. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. An ill-defined border with a broad zone of transition is a sign of aggressive growth (1). Infection is seen in all ages. Once we have decided whether a bone lesion is sclerotic or osteolytic and whether it has a well-defined or ill-defined margins, the next question should be: how old is the patient? The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. 2021;13(22):5711. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Donald Resnick, Mark J. Kransdorf. (A) Small radiolucent lesion exhibiting a thin sclerotic border (arrow) is present in the lateral cortex of the distal tibia of a 13-year-old boy. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. There are no calcifications. There are calcified strands within the soft tissues. Case Report Med. Age is the most important clinical clue in differentiating possible bone tumors.There are many ways of splitting age groups, as can be seen in the table, where the morphology of a bone lesion is combined with the age of the patient. Usually stress fractures are easy to recognize. Acute osteomyelitis is characterised by osteolysis. This is especially true when the injury involves the spine, hip, knees, or ankle. Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition In 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered Solitary sclerotic bone lesion. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. In order to classify osteolytic lesions as well-defined or ill-defined, we need to look at the zone of transition between the lesion and the adjacent normal bone. 1991;167(9):549-52. Here a chondrosarcoma of the left iliac bone. One can then apply various features of the lesions to this differential, and exclude some things, elevate some things, and downgrade others in the differential. A cold bone scan is helpful in distinguishing the bone island from a sclerotic metastasis, whereas a warm bone scan is nondiagnostic. (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 ). Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-22391. In juxta-articular localisation, the reactive sclerosis may be absent. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. diffuse sclerotic metastases to the pelvis, sacrum and femurs. These lesions usually regress spontaneously and may then become sclerotic. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Fundamentals of diagnostic radiology. This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone. 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. Journal of Bone Oncology. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. AJR Am J Roentgenol. 1, The classic bone island has a spiculated or paintbrush border and is much denser on CT than a osteoblastic metastasis. Radiologe. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. A surface osteosarcoma could be considered in the differential diagnosis. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? Enchondroma, the most commonly encountered lesion of the phalanges. Localisation: femur, tibia, hands and feet, spine (arch). Rapid growth of the mineralized mass is not uncommon. If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). This is consistent with the diagnosis of a reactive process like myositis ossificans. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. Matching the degradation rate of the materials with neo bone formation remains a challenge for bone-repairing materials. This part corresponds to a zone of high SI on T2-WI with FS on the right. Polyostotic lesions > 30 years 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. Here an image of a patient with chronic osteomyelitis. This is extremely common in Pagets disease but extremely uncommon with a blastic metastasis. (2007) ISBN: 9780781779302 -. A brain MRI can . There are two patterns of periosteal reaction: a benign and an aggressive type. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. Here a well-defined mixed sclerotic-lytic lesion of the left iliac bone. Mirels H. Metastatic Disease in Long Bones: A Proposed Scoring System for Diagnosing Impending Pathologic Fractures. How should one approach sclerotic bone disease? Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. 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. General Considerations Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 Teaching Point: Metastasis is the most common malignant rib lesion. These are inert filled-in non-ossifying fibromas. 2018;2018:1-5. mutation, and both sclerotic and lytic bone lesions together for the first time. Ulano A, Bredella M, Burke P et al. Secondary bone cancer is much more common than primary bone . Ossifications or calcifications can be present in variable amounts. A disadvantage of MRI is that the detection is poor in bones with a small marrow cavity such as the ribs and these bones are better investigated with CT 2,3. CT-HU has stronger correlations with DEXA than MRI measurements. Many important signaling . It can also be proven histologically. The mean and maximum attenuation were measured in Hounsfield units. 2017;11(1):321. The juxtacortical mass has a high SI and lobulated contours. Here a rather wel-defined eccentric lesion which is predominantly sclerotic. Osteoid matrix 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. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. Sclerotic bone metastases. Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. Therefore, MRI and bone scan were performed. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. In some cases however the osteolytic nidus can be visible on the radiograph (figure). This feature differentiates it from a juxtacortical tumor. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. In skeletally mature patients, GCTs begin in the metaphysics and extend deep to the subchondral bone plate of the articular surface. The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. 1. 2. 2. These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. Radiographs are specific but suffer from low sensitivity 1. by Clyde A. Helms 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. Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. An aggressive type is seen in malignant tumors, but also in benign lesions with aggressive behavior, such as infections and eosinophilic granuloma. A 30-year-old woman underwent a CT of the pelvis for endometriosis and an incidental lesion was found in the sacrum. World J Radiol. Non-ossifying fibroma (NOF) can be encoutered occasionally as a partial or completely sclerotic lesion. Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. Metastases are the most common malignant bone tumors. Osteosarcoma (2) Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. In breast cancer, metastases may present as lytic lesions that may become sclerotic expressing a favourable response to chemotherapy. Ewing sarcoma with lamellated and focally interrupted periosteal reaction. 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. 2. AJR Am J Roentgenol. 2016;207(2):362-8. Here two patients with a bizar parosteal osteochondromatous proliferation (BPOP), also called Nora's lesion. Gulati V, Chalian M, Yi J, Thakur U, Chhabra A. Sclerotic Bone Lesions Caused by Non-Infectious and Non-Neoplastic Diseases: A Review of the Imaging and Clinicopathologic Findings. Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). (2007) ISBN:0781765188. Here images of a patient with breast cancer. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). <-Lucent Lesions of Bone | Periosteal Reaction->. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. Typical presentation: well-defined osteolytic lesion in tarsal bone, patella or epiphysis of a long bone in a 20-year old with pain and swelling in a joint. Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. 3. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. About Us; Staff; Camps; Scuba. 2016;207(2):362-8. sclerosing osteomyelitis of Garr, aggressive features might require an oncological referral and/or biopsy 1, history of malignancy will almost always require additional imaging, follow-up or oncologic referral, high CT attenuation values might help in the differentiation of bone island from osteoblastic metastases 5 but attenuation values should not be used exclusively for the assessment of sclerotic bone lesions 6, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Sclerotic means that the lesions are slow-growing changes to your bone that happen very gradually over time. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Fibrous dysplasia, enchondromas, EG, Mets and myeloma, Hyperparathyroidism, Infection. MRI also may detect the nidus, combined with abundant bone marrow and soft tissue edema. Both imaging modalities achieved only a moderate correlation with DEXA. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. Several genes have been discovered that, when disrupted, result in specific types . 11. This is a routine medical imaging report. Some prefer to divide patients into two age groups: 30 years. 5 Biopsy should be considered in atypical cases or in high-risk patients with primary malignancies associated with osteoblastic metastatic disease. Unable to process the form. The pathogenesis of myeloma-related bone disease (MBD) is the imbalance of the bone-remodeling process, which results from osteoclast activation, osteoblast suppression, and the immunosuppressed bone marrow microenvironment. Many lesions can be located in both or move from the metaphysis to the diaphysis during growth. Differential diagnosis based on the periosteal reaction and the extensive edema: Here a patient with a juxtacortical sclerotic mass of the proximal humerus (left). Bone metastases have a predilection for hematopoietic marrow sites: spine, pelvis, ribs, cranium and proximal long bones: femur, humerus. The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. Sclerosis can also be reactive, e.g. MR usually shows a large amount of reactive changes in bone and soft tissue. Another finding classic for Pagets disease is that it almost always starts at one end of a bone and then spreads toward the other end of the bone. The evaluation of a solitary bony lesion in the spine may be more challenging and will often require additional diagnostic testing if benign imaging features are not present on MRI. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. Sarcoidosis is a multi-system disease with a range of . Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . Frequently encountered as a coincidental finding and can be found in any bone. The MR image shows that the lesion has lobulated contours and nodular enhancement. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. There are a number of other helpful findings you can look for that can help you to cone in on or away from specific entities in one of these differential lists. The image shows a calcified lesion in the proximal tibia without suspicious features. AJR Am J Roentgenol. 7A, and 7B ). 2019;15:100205. Brant WE, Helms CA. It classically presents with nocturnal pain in young patients, painful scoliosis, and marked relief from NSAIDs (nonsteroidal anti-inflammatory drugs). Imaging: Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Etiology BackgroundCongenital generalized lipodystrophy (CGL) is a rare disease. 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. Therefore, knowing the homogeneously sclerotic bone lesions can be useful, such as enostosis (bone island) (), osteoma (), and callus or bone graft.The plain radiography and CT images of enostosis consist of a circular or oblong area of dense bone with an irregular and speculated margin, which have been . 10. In patients In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered On the left three bone lesions with a narrow zone of transition. Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. Radiological atlas of bone tumours of the Netherlands Committee on Bone Tumors 2022;51(9):1743-64. It is a feature of malignant bone tumors. Osteomyelitis is a mimicker of various benign and malignant bone tumors and reactive processes that may be accompanied by reactive sclerosis. Park S, Lee I, Cho K et al. Based on the morphology and the age of the patients, these lesions are benign. Sclerotic bone lesions are rare; commonly affects the axial skeleton (pelvis, spine, skull, ribs) and the patients are often symptomatic as opposed to the patients with lytic lesions who rarely have any symptoms. Well, generally, it means that it is due to a fairly slow-growing process. Bone scintigraphy (99mTc MDP) is very sensitive for the detection of osteoblastic providing information on osteoblastic activity but suffers from specificity with a false-positivity rate ranging up to 40% 1. 9. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Complete envelopment may occur. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. DD: old SBC. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. 7. If there are multiple or polyostotic lesions, the differential diagnosis must be adjusted. The signal intensity on MR depends on the amount of calcifications and ossifications and fibrous tissue (low SI) and cystic components (high SI on T2). Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Subungual exostoses are bony projections which arise from the dorsal surface of the distal phalanx, most commonly of the hallux. Amorphous mineralisation is present in most lesions. Here a patient with a broad-based osteochondroma. A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. Centrally there is an ill-defined osteolytic area. 2003;415(415 Suppl):S4-13. Infections, a common tumor mimicker, are seen in any age group. Contact Information and Hours. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. Hall F & Gore S. Osteosclerotic Myeloma Variants. This occurs in early knee osteoarthritis and indicates the potential for cartilage loss and misalignment of a knee compartment. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. The most common appearance is the mixed lytic-sclerotic. Notice that the mineralization is predominantly in the periphery of the mass and that there is a lucent zone between the mass and the cortical bone. Non-ossifying fibroma which has been filled in. Bone islands can be large at presentation. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. Urgency: Routine. Osteoblastic metastases (2) Coronal MR image demonstrates subtle low intensity line representing the fracture. Bone islands demonstrate uniformly low A juxtacortical chondrosarcoma has be considered in the differential diagnosis when a mineralized lesion adjacent to the cortical bone is seen. 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. In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. 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. Growth has been demonstrated well after skeletal maturity. Materials and Methods 1. Wide zone of transition Generic Differential Diagnosis of Sclerotic Bone Lesions. They can affect any bone and be either benign (harmless) or malignant (cancerous). Here two other lesions in different patients that proved to be chondrosarcoma. Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. 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. Mnemonic for multiple oseolytic lesions: FEEMHI: In most cases of osteoid osteoma the radiographic appearance is determined by the reactive sclerosis. Spine (Phila Pa 1976). Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. If the osteonecrosis is located in the epiphysis, the term avascular osteonecrosis is used. Notice the lytic peripheral part with subtle calcifications.
