Acetabular protrusion secondary to pelvic hemangioma. A case report and review of the literature.

Hemangioma of the pelvis is a rare benign tumor. Acetabular protrusion associated with a hemangioma has not been reported previously. A 12 year old girl who had a right sided pelvic hemangioma and protrusio acetabulae was treated over an eight year period. The patient had deterioration of hip function due to progressive acetabular protrusion. Radiotherapy did not appear to prevent tumor infiltration into bone and surrounding soft tissue.
