sclerotic bone lesions radiology
Here CT-images of a patient with prostate cancer. Case 2: sclerotic metastases from prostate cancer, Generalised increased bone density (mnemonic). This is consistent with the diagnosis of a reactive process like myositis ossificans. It is most commonly located in the outer table of the neurocranium or in a paranasal sinus. 7A, and 7B ). Radiological atlas of bone tumours of the Netherlands Committee on Bone Tumors In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. It may be spiculated and interrupted - sometimes there is a Codman's triangle. A high grade chondrosarcoma must be considered in the differential diagnosis. 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. The MR image shows that the lesion has lobulated contours and nodular enhancement. In the active phase there is multilaminar periosteal reaction and bone and soft tissue edema. 2022;51(9):1743-64. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. 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. 11. Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. 4. 4, Although usually stable in size, bone islands may increase or decrease in size or disappear. 6. Most of the time, sclerotic lesions are benign. Diffuse bony sclerosis (mnemonic) Last revised by Joshua Yap on 28 Jun 2022 Edit article Citation, DOI & article data A mnemonic for remembering the causes of diffuse bony sclerosis is: 3 M's PROOF Mnemonic 3 M's PROOF M: malignancy metastases ( osteoblastic metastases) lymphoma leukemia M: myelofibrosis M: mastocytosis S: sickle cell disease Ulano A, Bredella M, Burke P et al. MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. The use of radiological imaging in medical care dates back to 1895 when Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . Ask the patient or the clinician about this. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. A chondrosarcoma was diagnosed at biopsy. 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. Infections, a common tumor mimicker, are seen in any age group. Non-ossifying fibroma which has been filled in. Differentiating between a diaphyseal and a metaphyseal location is not always possible. Infection is seen in all ages. Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. The lesion shows increased uptake of the tracer in the bone scan (arrow in Fig. A popular mnemonic to help remember causes of focal sclerotic bony lesions is: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 2019;15:100205. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. This represents a thick cartilage cap. Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. Diagnostic brain imaging tests can assess bone fractures, structural problems, blood vessel abnormalities, and changes in brain metabolism. Sclerotic means that the lesions are slow-growing changes to your bone that happen very gradually over time. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. Radiologe. 5. 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. 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. 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. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. 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. mutation, and both sclerotic and lytic bone lesions together for the first time. However, a specific density range has not been specified for those terms 1. Usually new bone is added to one side of the cortex only. found incidentally on the imaging studies. The differential diagnosis of bone lesions that result in bony sclerosis will be given. The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Notice the numerous predominantly osteoblastic metastases. Multiple enchondromas are seen in Morbus Ollier. Fundamentals of diagnostic radiology. Differential Diagnosis of Diffuse Sclerotic Bone Lesions. The differential diagnosis of solitary sclerotic bone lesions can be narrowed down according to the following factors 1-3: cartilaginous matrix (rings and arcs appearance). Chang C, Garner H, Ahlawat S et al. Typical presentation: central lesion in metaphysis or diaphysis with a well defined serpentiginous border. 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. Fisher C, DiPaola C, Ryken T et al. CT-HU has stronger correlations with DEXA than MRI measurements. Donald Resnick, Mark J. Kransdorf. Chrondroid tumors are more frequently encountered than bone infarcts. Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. Based on the morphology and the age of the patients, these lesions are benign. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . MRI shows large tumor within the bone and permeative growth through the Haversian channels accompanied by a large soft tissue mass, which is barely visible on the X-ray. A sclerotic lesion is an unusual hardening or thickening of your bone. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. Growth has been demonstrated well after skeletal maturity. These lesions were possibly misinterpreted as new when applying WHO criteria. Notice the homogeneous thickening of the cortical bone. Cancers (Basel). 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). Check for errors and try again. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Bone marrow edema can happen with fractures and other serious bone or joint injuries. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. Resonance Imaging Saeed M. Bafaraj . The images show on the left a typical osteolytic NOF with a sharp sclerotic border. In general, they're slow-growing.. Aggressive periosteal reaction 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. CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. 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. CT Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. The contour of the involved bone is usually normal or with mild expansive remodelling. Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. 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. It grows primarily into the surrounding soft tissues, but may also infiltrate into the bone marrow. (white arrows). Click here for more detailed information about NOF. Notice that the cortical bone extends into the lesion. Localisation: femur, tibia, hands and feet, spine (arch). This is a routine medical imaging report. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) 2010;35(22):E1221-9. Here two other lesions in different patients that proved to be chondrosarcoma. Rib metastases may be osteolytic, sclerotic, or mixed. It is barely visible within the bone, but an agressive periostitis is seen (arrow). However, a specific density range has not been specified for those terms 1. 1. Urgency: Routine. Here images of a patient with prostate cancer. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. Materials and Methods Both of these entities may have an aggressive growth pattern. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. Signed by [redacted] on 1/17/2020 11:42 AM Narrative Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. AJR Am J Roentgenol. Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. Usually stress fractures are easy to recognize. Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. Most bone tumors are solitary lesions. MRI of the sacrum: axial T1-weighted (T1w; Fig. Osteoid matrix in osseus tumors like osteoid osteomas and osteosarcomas. 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. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. AJR Am J Roentgenol. by Clyde A. Helms Here a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet The major part of the lesion consists of reactive sclerosis. 105-118. Bone scan shows no high activity, opposed to low-grade intraosseous osteosarcoma. Frequently encountered as a coincidental finding and can be found in any bone. PET features high sensitivity in the detection of bone metastases especially 18 NaF-PET is suitable for the detection of sclerotic metastases since it shows tracer uptake in locations with osteoblastic activity and is more accurate than FDG-PET 3. Here two patients with a bizar parosteal osteochondromatous proliferation (BPOP), also called Nora's lesion. Mirels H. Metastatic Disease in Long Bones: A Proposed Scoring System for Diagnosing Impending Pathologic Fractures. Here images of an osteosarcoma in the right femur. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. Most commonly encountered bone tumor in the small bones of the hand and foot. 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. <-Lucent Lesions of Bone | Periosteal Reaction->. 1. The mean and maximum attenuation were measured in Hounsfield units. Ossifications or calcifications can be present in variable amounts. Causes: corticosteroid use, sickle cell disease, trauma, Gaucher's disease, renal transplantation. 2021;216(4):1022-30. 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. 2020;60(Suppl 1):1-16. 7. 3. 2021;216(4):1022-30. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Osteosarcoma, chondrosarcoma, and Ewing's sarcoma are the most common types of bone cancer. MRI also may detect the nidus, combined with abundant bone marrow and soft tissue edema. 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. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. 2019;290(1):146-54. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. Lumbar CT-HU has the highest pooled correlation (r 2 =0.6) with both spine DEXA and lowest skeletal t-score followed by lumbar CT-HU with hip DEXA (r 2 =0.5) and lumbar MRI with hip (r 2 =0.44) and spine (r 2 =0.41) DEXA. Osteoblastic Metastatic Lesions. 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 -. Complete destruction may be seen in high-grade malignant lesions, but also in locally aggressive benign lesions like EG and osteomyelitis. AJR 2005; 185:915-924. Osteoblastic bone metastases are characterized by increased bone formation 2. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan.

Centrally there is an ill-defined osteolytic area. 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 Nancy M. Major, Clyde A. Helms and William J. Richardson. Osteochondroma is a bony protrusion covered by a cartilaginous cap. 2003;415(415 Suppl):S4-13. Radiographs are specific but suffer from low sensitivity 1. Semin. by Mulder JD et al Edema often present in the surrounding bone marrow. 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. The mnemonic I VINDICATE is a commonly used mnemonic for the differential diagnostis of any radiological lesion. Enchondroma, the most commonly encountered lesion of the phalanges. When considering trauma as a cause for sclerotic lesions, remember to check and see if the areas involved are areas in the typical distribution for stress fractures. The image on the right is of a different patient who has an old NOF that shows complete fill in. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. The illustration on the left shows the preferred locations of the most common bone tumors. 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? in Ewing's sarcoma or lymphoma. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. In some cases however the osteolytic nidus can be visible on the radiograph (figure). If the patient had fever and a proper clinical setting, osteomyelitis would be in the differential diagnosis. FIGURE 2.7 Computed tomography of osteoid osteoma. Fundamentals of Skeletal Radiology, second edition Small osteolytic lesion (up to 1.5 cm) with or without central calcification. 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. In breast cancer, metastases may present as lytic lesions that may become sclerotic expressing a favourable response to chemotherapy. Skeletal Radiol. Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . Distinct phenotypes are described: osteoblastic, the more common osteolytic and mixed. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. As part of the test, a healthcare professional takes a sample of the CSF D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. Degenerative subchondral cyst: epiphyseal, Chondroid matrix in cartilaginous tumors like enchondromas and chondrosarcomsa. 1988;17(2):101-5. Infection with a multilayered periosteal reaction. The X-ray features were divided into two groups according to typical and atypical skeletal lesions. Click here for more examples of enchondromas. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases. Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. Etiology Sclerotic bone metastases. Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. 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. 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. 2017;11(1):321. Office Phone: (517) 205-6750. Cancers (Basel). Sclerosis is present from either tumor new bone formation or reactive sclerosis. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. 5. Here a lesion located in the epi- and metaphysis of the proximal humerus. Solitary lucent lesions in bone with a distinct margin are generally called "geographic" lesions, whether or not they have a sclerotic rim. Not infrequently encountered as coincidental finding at later age. (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. 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 1991;167(9):549-52. None of the patients had undergone prior treatment for the metastases. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. Notice the lytic peripheral part with subtle calcifications. Radiographic or CT features that suggest malignancy: Use MRI with water-sensitive sequence (T2 FS) to determine cartilage cap thickness. 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. Bone scintigraphy can be either negative or show limited uptake. 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. In most cases of osteoid osteoma the radiographic appearance is determined by the reactive sclerosis. Subchondral bone attrition is the flattening or depression of the bone surface that forms part of a joint. At Henry Ford Orthopaedics in Chelsea our mission is to provide personalized treatment plans specific to each patient, to ensure the best possible outcome. Notice that in all three patients, the growth plates have not yet closed. 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.
