Haemorrhage associated with meningioma: a case report and review of the literature.

A case of haemorrhage into a parasagittal meningioma treated by surgical resection is presented. A review of the literature found 43 additional cases of meningioma associated with haemorrhage. By correlating these cases with those from another large series of meningiomas classified by histological type and location, an estimation of the "relative bleeding tendency" of certain classes of meningiomas was made. Haemorrhage associated with meningioma is a serious complication and proper treatment consists of evacuation of the haematoma with resection of tumour.
