Osteochondromas are a relatively common imaging finding, accounting for 10-15% of all bone tumors and approximately 35% of all benign bone tumors. Although usually thought of as a benign bone tumor, they may be thought of as a developmental anomaly. They are frequently asymptomatic and have very low malignant potential if sporadic and solitary Osteochondroma is the most common benign tumor or tumorlike lesion of bone. The radiographic appearance of this tumor is often diagnostic and reflects its pathologic characteristics, that is, a lesion composed of cortical and medullary bone with an overlying hyaline cartilage cap Osteochondroma represents the most common bone tumor and is a developmental lesion rather than a true neoplasm. It constitutes 20%-50% of all benign bone tumors and 10%-15% of all bone tumors. Its radiologic features are often pathognomonic and identically reflect its pathologic appearance
Imaging of Osteochondroma: Variants and Complications with Radiologic-Pathologic Correlation1 Mark D. Murphey, MD • James J. Choi, MD • Mark J. Kransdorf, MD Donald J. Flemming, CDR, MC, USN • Frances H. Gannon, MD Osteochondroma represents the most common bone tumor and is a develop-mental lesion rather than a true neoplasm An osteochondroma arises from the medial aspect of the distal femoral diaphysis, extending away from the joint. It has a small cartilage cap, and associated with no pathological fracture. Minimal surrounding muscular edema most likely mechanical in nature . The prevalence of reported malignant transformation varies from less than 1% for solitary osteochondromas and 2%-5% for hereditary multiple exostosis (1, 2) There is a bilobed, or two adjacent osteochondromas arising from the left posteromedial femur, measuring approximately 8.8 cm vertically. The proximal end of the lesion commences approximately 14.5cm superior to the knee joint. The posterior component measures approximately 2.5 cm in diameter in the medial lesion measures approximately 4 cm
Osteochondroma is the most common benign bone tumor and the most common skeletal neoplasm They account for approximately 35% of all benign bone tumors and 9% of all bone tumors They are cartilage-capped bony projections from the external surface of a bon Exostoses are defined as benign growths of bone extending outwards from the surface of a bone. It can occur in any bone and be triggered by a number of factors. There are a number of examples of exostoses that occur due to local irritant stimuli: ivory exostosis. exostosis of the external auditory canal (surfer's ear Diagnosis of secondary chondrosarcoma arising in osteochondroma can be challenging and requires correlation with clinical and imaging findings ( Mod Pathol 2012;25:1275, Radiology 2010;255:857, Oncogene 2012;31:1095 ) Tumor growth and thickening of the cartilage cap (usually > 2 cm) are suggestive of malignant transformation in skeletally. Osteochondromas can be complicated by mechanical irritation, compression or injury of adjacent structures, fracture, malignant transformation, and postoperative recurrence. Magnetic resonance imaging represents the most valuable imaging modality in symptomatic cases, because it can demonstrate typic
Osteochondromas are the most common primary benign bone tumor, accounting for 20%-50% of all benign bone tumors and 10-15% of all bone tumors Osteochondromas are the most commonly found benign neoplasms of bone, typically affecting long bones, most frequently the distal femur and proximal tibia. The lesion has core and cap that contains both cortical and medullary bone and hyaline cartilage respectively. Multiple osteochondromas are associated with hereditary multiple exostoses
An osteochondroma is a benign (noncancerous) tumor that develops during childhood or adolescence. It is an abnormal growth that forms on the surface of a bone near the growth plate. Growth plates are areas of developing cartilage tissue near the ends of long bones in children . Cartilage sequence MRI showed an osteochondroma with a 5 mm cartilage cap. There were no suspicious features of malignancy Osteochondromas are the most common benign tumors of the bones. The tumors take the form of cartilage-capped bony projections or outgrowth on the surface of bones exostoses. It is characterized as a type of overgrowth that can occur in any bone where cartilage forms bone. Tumors most commonly affect long bones about the knee and in the forearm Radiology department of the Onze Lieve Vrouwe Gasthuis, Amsterdam and the Rijnland hospital, Leiderdorp, the Netherlands. Publicationdate 2013-11-01. Osteochondroma usually presents as an incidental finding, or in the form of a syndrome with multiple osteochondromas
CT of the chest was performed for further evaluation and this confirmed the diagnosis of osteochondroma, with a well-delineated cartilaginous cap being demonstrated. The patient returned after 3 months with a sudden increase in pain. Plain chest radiographs revealed a small pneumothorax on the right side, in addition to the osteochondroma Abstract. Computed tomography (CT) was performed prior to surgery on six patients with osteochondroma and six with chondrosarcoma. Criteria for distinguishing these two types of cartilage tumors were developed from classical radiological descriptions and known pathological characteristics. Application of these criteria to CT images permitted. Imaging: Osteochondroma is a bony excrescence with well-defined limits, having a thin outer cortex and an internal cancellous structure. The pathognomonic radiographic feature is that the cortex of the host bone flares into the cortex of the osteochondroma, and the cancellous bone of the osteochondroma blends with the cancellous bone of the metaphysis Osteochondroma Radiology.OrthopaedicsOne Images.In: OrthopaedicsOne - The Orthopaedic Knowledge Network.Created Oct 22, 2010 12:11.

Osteochondroma. A 12-year-old boy presents to his pediatrician for a bony mass on his left leg. He denies any trauma to the area and it is not associated with pain. Physical examination demonstrates a palpable painless mass close to the knee joint. A radiograph of the knee demonstrates a bony outgrowth with clear, regular margins Osteochondroma & Multiple Hereditary Exostosis. Osteochondromas are benign chondrogenic lesions derived from aberrant cartilage from the perichondral ring that may take the form of solitary osteochondroma, or Multiple Hereditary Exostosis. Patients typically present between the ages of 10 and 30 with a painless mass
Osteochondroma, also known as osteocartilaginous exostosis is a benign cartilage forming tumor that usually develops in long bones and relatively uncommon in the craniofacial region. Both the condyle and coronoid tip being the most common sites of occurrence in the mandible, it rarely appears at the symphysis region. Here, we describe a case of osteochondroma arising from the left. Osteochondroma, or osteocartilaginous exostosis, is the most common skeletal neoplasm. The cartilage capped subperiosteal bone projection accounts for 20-50% of benign bone tumors and 10-15% of all bone tumors.Osteochondromas are most likely caused by either a congenital defect or trauma of the perichondrium which results in the herniation of a fragment of the epiphyseal growth plate through.
Case Discussion. Spinal osteochondromas are rare, but when the spine is involved by exostosis cervical spine is most commonly involved part of the spine. It is believed that C2 is the most common vertebra to be involved by solitary osteochondroma.

Secondary synovial osteochondromatosis (SOC) is a rare disorder caused by a variety of joint disorders. Two unusual cases of secondary SOC are presented. The first patient is a 43-year-old man with extensive SOC developing within a bursa surrounding an osteochondroma of the pubic bone. The second pa Osteochondroma is the most common benign chondrogenic lesion of the skeleton. Arising mostly in the long bones of the appendicular skeleton but may involve flat bones as well. Calcaneum however, is an uncommon site. True incidence is still unknown as many are asymptomatic, growing during childhood through adolescent until skeletal maturity 122 Osteochondroma versus Chondrosarcoma. Malignant transformation to chondrosarcoma is seen in 1% of patients with solitary osteochondromas and 3 to 5% of patients with hereditary multiple exostoses. 1 Osteochondromas that grow or cause pain after skeletal maturity should be suspected of malignant degeneration. Features that can be used to diagnose malignant degeneration by computed. Similar to osteochondroma, DEH is diagnosed prior to 15 years of age and the growth of lesions end at puberty, when the growth plates close. Metachondromatosis is a rare disorder that exhibit symptoms of both multiple osteochondromas and enchondromas in children and is also inherited in autosomal dominant mode
Solitary osteochondroma. CT scan of the same sessile osteochondroma of the humerus as in Image 6. Magnetic resonance imaging (MRI) is needed only in cases where malignancy is a concern or where relevant soft-tissue anatomy must be delineated.

Introduction Osteochondromas, also known as exostoses, are the most common primary bone tumors comprising more than one third of all benign bone tumors ().They can be solitary (90% of cases) or multiple in the form of hereditary multiple exostosis (HME) (10% of cases) ().Osteochondromas are located frequently in the long bones and rarely involve.
Both CT and MRI are useful imaging techniques to differentiate osteochondroma with large bursa formation from malignant transformation of osteochondroma. The lesser trochanter of the femur is the second most common location of large bursa formation. Hospital Build Middle East, Congress of the Brain Tumor Radiology in Neuro-oncology Society. Osteochondroma (Exostosis) Osteochondroma is the most common type of non-cancerous (benign) bone tumor. An osteochondroma is a hard mass of cartilage and bone that generally appears near the growth plate (a layer of cartilage at the ends of a child's long bones). The majority of children with an osteochondroma only have a single tumor An osteochondroma is the most common type of harmless bone tumor. It starts in the cartilage that cushions bones. It can appear on the bones of the arms and legs. Sometimes it happens on the pelvic bones and shoulder blades. An osteochondroma usually stops growing when a person reaches full height Extraosseous Intra-Articular Osteochondroma.

Osteochondroma of the fifth rib resulting in recurrent hemothorax Osteochondroma (Fig. 2A, 2B) is the most common primary benign neoplasm of the scapula with an incidence of 4.6% [ 3 ]. Usually, it is a single lesion located on the anterior surface of the scapular body. Patients with osteochondroma complain of a snapping sensation when internally rotating and abducting their arm Hereditary multiple osteochondromas (HMO) is an autosomal dominant disease diagnosed by the presence of two or more than two osteochondromas on radiographs. The majority of cases are asymptomatic. The presence of bony growth, pain, and compression of the surrounding structure are the usual presentations. Malignant transformation into chondrosarcoma is the most feared complication Bizarre parosteal osteochondromatous proliferation (BPOP) is a rare lesion that occurs most commonly in the hands and feet. This lesion grows rapidly and has aggressive features on imaging studies as well as confusion findings on histopathology, leading to many errors in diagnosis and potentially inappropriate treatments
