Masson's vegetant hemangioendothelioma: case report and literature review.

Masson's vegetant intravascular hemangioendothelioma has only been reported intracranially in 12 patients. The pathological diagnosis is important given its benign natural history. We report the 13th case in a woman who presented with headaches and dysphasia. A thorough literature review is presented and an appropriate management strategy is proposed.
