Two-step treatment of a giant skull vault hemangioma: A rare case report and literature review

Abstract

Skull vault hemangiomas are benign vascular tumours of the calvaria that are usually asymptomatic or present as firm, painless lumps. We present a case of a 59-year-old female with a giant intraosseous calvarial hemangioma that was admitted in our department with a palpable mass over the left frontoparietal region, personality changes and impaired emotional and cognitive functions. The patient was treated with a two-step approach involving endovascular and surgical treatment, and suffered two rare, but recognized complications, a contrecoup intracerebral haemorrhage and valproate-induced stupor and parkinsonism. At the 6-month follow-up, the patient had complete recovery with a good neurological outcome.
