Giant calvarial intraosseous angiolipoma: a case report and review of the literature.

Intraosseous angiolipomas are very rare tumors occurring most commonly in the ribs and mandible. Only two cases with intracranial involvement have been reported in the literature. We report a case of a giant calvarial angiolipoma and its surgical treatment in a 30-year-old female who presented with a slowly expanding skull mass and discuss relevant radiological, histological and surgical findings.
