Epithelioid hemangioma is a rare, histologically benign but locally aggressive primary vascular neoplasm that can rarely arise in bone. Mainstay treatment is surgical resection or curettage with bone grafting. We report a novel multidisciplinary, joint-sparing treatment approach for an epithelioid hemangioma of bone arising in the acetabulum causing severe thinning of the subchondral bone plate. After 4 sessions of transarterial bland particle and ethanol embolization, the resultant increased ossification of the tumor allowed preservation of the articular surface during surgical resection. Imaging follow-up 14 months after surgical resection showed no evidence of recurrence and continued ossification of the portions of the lesion treated only with embolization.
