Intraosseous haemangioma of the proximal femur: imaging findings.

Haemangiomas of bone are uncommon lesions, accounting for approximately 1% of all primary bone tumours. The most frequent sites of involvement are the calvaria and the vertebral column. When haemangiomas involve long tubular bones, they are usually found in the diaphysis or metadiaphysis. Juxta-articular or epiphyseal location for a long bone haemangioma is rare. We present the imaging findings in a case of a histopathologically proven juxta-articular intraosseous haemangioma of the proximal femur. We believe ours is the first report of a haemangioma involving the proximal end of the femur.
