MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. Case Report Med. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. 5 Biopsy should be considered in atypical cases or in high-risk patients with primary malignancies associated with osteoblastic metastatic disease. Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. Aggressive periosteal reaction 9. After an injury, different types of fluid can build up in a bone. Radionuclide bone scan shows a classic "double density" sign of osteoid osteoma located in the tibia: markedly increased radioactivity in the center ( arrow) is related to the nidus, less active areas ( arrowheads) represent reactive sclerosis. Here Melorrheostosis of the ulna with the appearance of candle wax. Bone islands can be large at presentation. . Here an illustration of the most common sclerotic bone tumors. Impact of Sclerotic. Axial imaging for differentiation from Brodie abscess, osteoblastoma, stress fracture. In the active phase there is multilaminar periosteal reaction and bone and soft tissue edema. Typical presentation: central lesion in metaphysis or diaphysis with a well defined serpentiginous border. 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. However, a specific density range has not been specified for those terms 1. Radiographs are specific but suffer from low sensitivity 1. Melorrheostosis is a dysplasia of the bone, characterized by apposition of mature bone on the outer or inner surface of cortical bone. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. Here a well-defined mixed sclerotic-lytic lesion of the left iliac bone. Click here for more examples of chondroblastoma. Radiology. Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 Many important signaling . In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. These lesions usually regress spontaneously and may then become sclerotic. Notice the numerous ill-defined osteoblastic metastases. 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. Diagnostic brain imaging tests can assess bone fractures, structural problems, blood vessel abnormalities, and changes in brain metabolism. 33.1d). Amsterdam: Elsevier; 1993. If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). Here an image of a patient with chronic osteomyelitis. This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. Polyostotic lesions > 30 years 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. It can differentiate predominantly osteoblastic from osteolytic bone metastases 9 as well as easily demonstrate and assess complications such as pathological fractures or spinal cord compression 2,3. On CT sclerotic bone metastases typically present as hyperdense lesions, but display a lower density than bone islands 5. Bone Metastases: An Overview. 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 bone scan is also helpful to look for additional sites of increased uptake that may not have been imaged, such as multiple nontraumatic rib, calvarial, or long bone lesions, which would strongly suggest the diagnosis of metastatic disease. This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone. Osteoid matrix in osseus tumors like osteoid osteomas and osteosarcomas. Differentiating between a diaphyseal and a metaphyseal location is not always possible. Here a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. Rib metastases may be osteolytic, sclerotic, or mixed. Wide zone of transition The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). Osteoblastic Metastatic Lesions. 105-118. Contact Information and Hours. Enchondroma, the most commonly encountered lesion of the phalanges. {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Knipe H, Weerakkody Y, et al. However, a specific density range has not been specified for those terms 1. Check for errors and try again. A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together. Appendicitis - Pitfalls in US and CT diagnosis, Acute Abdomen in Gynaecology - Ultrasound, Transvaginal Ultrasound for Non-Gynaecological Conditions, Bi-RADS for Mammography and Ultrasound 2013, Coronary Artery Disease-Reporting and Data System, Contrast-enhanced MRA of peripheral vessels, Vascular Anomalies of Aorta, Pulmonary and Systemic vessels, Esophagus I: anatomy, rings, inflammation, Esophagus II: Strictures, Acute syndromes, Neoplasms and Vascular impressions, TI-RADS - Thyroid Imaging Reporting and Data System, How to Differentiate Carotid Obstructions, Periosteal or juxtacortical chondrosarcoma, Aneurysmal Bone Cyst: Concept, Controversy, Clinical Presentation, and Imaging, Bone Tumors and Tumorlike Conditions: Analysis with Conventional Radiography. Centrally there is an ill-defined osteolytic area. 1. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. . The image on the right is of a different patient who has an old NOF that shows complete fill in. 4, Although usually stable in size, bone islands may increase or decrease in size or disappear. A mean CT attenuation threshold of 885 HU and a maximum attenuation threshold of 1060 HU has been found supportive in the differentiation of untreated osteoblastic and bone island in one study 7, but the exclusive use of attenuation values for the assessment of sclerotic bone lesions has been discouraged 8. Diffuse bony sclerosis (mnemonic). The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. As you can see, by just dropping the items that tend to cause generalized sclerosis, we have generated a fairly good differential for focal lesions. 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. Chordoma is usually seen in the spine and base of the skull. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. BackgroundCongenital generalized lipodystrophy (CGL) is a rare disease. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet It may be spiculated and interrupted - sometimes there is a Codman's triangle. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. 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. Generally, this just follows common sense some lesions should logically be expected to be focal, others multifocal, and yet others diffuse or systemic. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. Differential diagnosis based on the periosteal reaction and the extensive edema: Here a patient with a juxtacortical sclerotic mass of the proximal humerus (left). The radiographic appearance and location are typical. The contour of the subchondral bone plate was maintained until day 3, but it was absorbed just under the cartilage defect from day 7 to 14. Focal sclerotic bony lesions (mnemonic). Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? -. The contour of the involved bone is usually normal or with mild expansive remodelling. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. 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. On the left three bone lesions with a narrow zone of transition. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Notice that many benign osteolytic lesions that are frequently seen in younger age groups may heal and appear as sclerotic lesions in the middle aged group. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. Age: most commonly seen in 10-25 years, but may occur in older patients. All images were evaluated for joint form, erosion, sclerosis, fat metaplasia and bone marrow oedema (BMO) by two independent readers. Click here for more information about bone island. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. Another approach to the differential diagnosis of sclerotic bone lesions is to use the mnemonic I VINDICATE, which means 'I clear myself from accusation'. This could very well be an enchondroma. 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. Differential diagnosis Top five location of bone tumors in alphabethic order: Aneurysmal Bone Cyst -tibia, femur, fibula, spine, humerusAdamantinoma -tibia shaft, mandibleChondroblastoma -femur, humerus, tibia, tarsal bone (calc), patellaChondromyxoid fibroma - tibia, femur, tarsal bone, phalanx foot, fibulaChondrosarcoma - femur, rib, iliac bone, humerus, tibiaChordoma -sacrococcygeal, spheno-occipital, cervical, lumbar, thoracicEosinophilic Granuloma -femur, skull, iliac bone, rib, vertebraEnchondroma -phalanges of hands and feet, femur, humerus, metacarpals, ribEwing's sarcoma - femur, iliac bone, fibula, rib, tibiaFibrous dysplasia - femur, tibia, rib, skull, humerusGiant Cell Tumor - femur, tibia, fibula, humerus, distal radiusHemangioma - spine, ribs, craniofacial bones, femur, tibiaLymphoma - femur, tibia, humerus, iliac bone, vertebraMetastases - vertebrae, ribs, pelvis, femur, humerusNon Ossifying Fibroma - tibia, femur, fibula, humerusOsteoid osteoma - femur, tibia, spine, tarsal bone, phalanxOsteoblastoma - spine, tarsal bone (calc), femur, tibia, humerusOsteochondroma - femur, humerus, tibia, fibula, pelvisOsteomyelitis - femur, tibia, humerus, fibula, radiusOsteosarcoma -femur, tibia, humerus, fibula, iliac boneSolitary Bone Cyst -proximal humerus, proximal femur, calcaneal bone, iliac bone. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Notice how easily MRI depicts these lesions. (2005) ISBN: 9780721602707 -. Resonance Imaging Saeed M. Bafaraj . A brain MRI can . The differential diagnosis of bone lesions that result in bony sclerosis will be given. Infection may be well-defined or ill-defined osteolytic, and even sclerotic. 4. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). Mild mass effect on adjacent lung, diaphragm, and liver. These are infections and eosinophilic granuloma. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. Mnemonic for multiple oseolytic lesions: FEEMHI: Parosteal osteosarcoma is a sarcoma that has it's origin on the surface of the bone. 14. Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. Bker S, Adams L, Bender Y et al.

Metastases are the most common malignant bone tumors. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. 2020;60(Suppl 1):1-16. 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. Particularly chronic osteomyelitis may have a sclerotic appearance. Most of the time, sclerotic lesions are benign. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. Subchondral bone attrition is the flattening or depression of the bone surface that forms part of a joint. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. 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. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. 2021;13(22):5711. At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. Mixed lytic/sclerotic lesion of right posterolateral 10 th rib, with extensive aggressive-appearing periostitis, as well as a multilobulated soft tissue component. Axial T1-weighted MR image shows homogeneous low signal intensity due to the compact bone apposition. Metastases and multiple myelomaIn patients > 40 years metastases and multiple myeloma are the most common bone tumors.Metastases under the age of 40 are extremely rare, unless a patient is known to have a primary malignancy.Metastases could be included in the differential diagnosis if a younger patient is known to have a malignancy, such as neuroblastoma, rhabdomyosarcoma or retinoblastoma. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. This could be an osteoblastic metastasis or an osteolytic metastasis that responded to chemotherapy. Plain films typically reveal lesions with moth-eaten or permeative pattern of the transition zone with irregular cortical destruction and an interrupted periosteal reaction with soft tissue extension. To determine if sclerotic bone lesions evident at body computed tomography (CT) are of value as a diagnostic criterion of tuberous sclerosis complex (TSC) and in the differentiation of TSC with lymphangioleiomyomatosis (LAM) from sporadic LAM.

Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Skeletal Radiol. Etiology However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. Non-ossifying fibroma which has been filled in. Publicationdate 2010-04-10 / update 2022-03-17. Click here for more detailed information about NOF. diffuse sclerotic metastases to the pelvis, sacrum and femurs. This is especially true when the injury involves the spine, hip, knees, or ankle. T2-weighted MR image reveals a lobulated mass with high signal intensity. Most primary bone tumors are seen in patients In patients > 30 years we must always include metastases and myeloma in the differential diagnosis. It is a feature of malignant bone tumors. Here images of a patient with breast cancer. Common: Metastases, multiple myeloma, multiple enchondromas. 2015;7(8):202-11. Well, generally, it means that it is due to a fairly slow-growing process. Complete envelopment may occur. 1991;167(9):549-52. ADVERTISEMENT: Supporters see fewer/no ads. Here CT-images of a patient with prostate cancer. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. These are inert filled-in non-ossifying fibromas. CT Ossifications or calcifications can be present in variable amounts. Usually it is a lesion of childhood or young adults. AJR Am J Roentgenol. 8. 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? Fibrous dysplasia can be monostotic or polyostotic. The mean and maximum attenuation were measured in Hounsfield units. 1988;17(2):101-5. Focal sclerotic bony lesions (mnemonic) Last revised by Daniel J Bell on 18 Feb 2019 Edit article Citation, DOI & article data A popular mnemonic to help remember causes of focal sclerotic bony lesions is: HOME LIFE Mnemonic H: healed non-ossifying fibroma (NOF) O: osteoma M: metastasis E: Ewing sarcoma L: lymphoma I: infection or infarct Cancers (Basel). Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. 2018;10(6):156. Notice that in all three patients, the growth plates have not yet closed. The image shows a calcified lesion in the proximal tibia without suspicious features. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Macedo F, Ladeira K, Pinho F et al. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. 2016;207(2):362-8. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. (2007) ISBN: 9780781779302 -. 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. World J Radiol. Generic Differential Diagnosis of Sclerotic Bone Lesions. {"url":"/signup-modal-props.json?lang=us"}, Yap K, Knipe H, Niknejad M, et al. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. It is most commonly located in the outer table of the neurocranium or in a paranasal sinus. 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. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. Brant WE, Helms CA. 2021;50(5):847-69. Typically presents as a lytic lesion in a flat bone, vertebra or diaphysis of long bone. (white arrows). If the process is slower growing, then the bone may have time to mount an offense and try to form a sclerotic area around the offender. A sclerotic lesion is an unusual hardening or thickening of your bone. 7. Well, generally, it means that it is due to a fairly slow-growing process. In the late stage of OA, the main feature is subchondral bone sclerosis, whose microarchitectural characteristics are elevated apparent density, increased bone volume, . Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. 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 lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. Tumor Pathology- Bone Lesion Bone Tumor Osteomyelitis When you identify a bone lesion, follow this basic checklist to help you accurately describe the lesion and narrow your differential diagnosis: Bone Tumors and Tumorlike Conditions: Analysis with Conventional Radiography Theodore T. Miller Radiology 2008 246:3, 662-674 Notice the lytic peripheral part with subtle calcifications. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. How should one approach sclerotic bone disease? Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). (2007) ISBN:0781765188. A chondrosarcoma was diagnosed at biopsy. Check for errors and try again. There is no calcification and lesions may be expansile. Breast cancer (usually mixed lytic/sclerotic), Bone islands do not have edema in the adjacent bone marrow or extension into surrounding soft tissue or adjacent bony destruction. AJR Am J Roentgenol. The differential diagnosis of bone lesions that result in bony sclerosis will be given. In general, they're slow-growing.. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases.
