Osteochondroma Radiology Reference Article Radiopaedia

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

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 Introduction Osteochondroma is the most common benign neoplasm of bone, representing 10%-15% of all primary bone tumors and up to 50% of the benign lesions (1). 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 Ultrasound and CT scan demonstrated an osteochondroma of the posterosuperior aspect of the medial clavicle compressing adjacent structures, including the right internal jugular vein and right common carotid artery. 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.

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.
