Meningioma of the foramen magnum presenting as subarachnoid haemorrhage and cerebellar haematoma.

An unusual case of a posterior fossa meningioma which caused subarachnoid haemorrhage (SAH) and cerebellar haematoma is presented. The possible causes of tumoral bleeding and the surprising clinical course are discussed in the context of the few similar cases reported in the literature. The importance of cerebral CT scan ning in SAH without angiographic demonstration of an aneurysm or angioma is emphasized.
