title: Intraarticular osteochondroma of shoulder: a case report.
abstract: Osteochondroma is a cartilage-capped osseous protrusion that arises from the surface of a bone. Osteochondroma occurs mostly in the metaphysis of long tubular bones such as the femur, tibia, and humerus. Osteochondroma is rare in the diaphysis and in the epiphysis. There was only one case in which a patient had a limited range of motion in the shoulder joint due to an intraarticular osteochondroma of the proximal humerus. We present a rare case of intraarticular osteochondroma involving the proximal humerus with pathologic findings and imaging features on computed tomography and magnetic resonance imaging.
