Multiple osteocartilaginous exostoses
Multiple osteocartilaginous exostoses, also known as multiple hereditary osteochondromata, familial osteochondromatosis or diaphyseal aclasis, is a hereditary autosomal-dominant disorder. There is a decided 2:1 male predilection. The knees, ankles, and shoulders are the sites most frequently affected by the development of multiple osteocartilaginous exostoses.
The radiographic presentation is characteristic according to whether the lesions are sessile, more frequent, with broad base attached to the cortex or pedunculated, with slender pedicle usually directed away from the neighboring growth plate.
