A huge frontal meningioma associated with intraoperative massive bleeding and severe brain swelling--case report.

A 58 year old female presented with progressive memory disturbance and personality change. Magnetic resonance (MR) imaging disclosed a huge mass lesion accompanied by prominent oedema in the right frontal lobe. Cerebral angiogram demonstrated a vascular-rich tumour and a major drainer through diploic vein. A right frontotemporal craniotomy was performed. We encountered massive bleeding from diploic vein and dura mater immediately at the craniotomy. We were also faced with severe brain swelling at the dural incision. The tumour was solid, highly vascularised, and fairly well demarcated. We performed total removal of the tumour as quickly as possible in order to reduce the intracranial hypertension and avoid the impending brain herniation. The patient had an uneventful recovery and was asymptomatic at 10 months follow-up. Copyright 2001 Harcourt Publishers Ltd.
