Coexistence of an intracranial meningioma and an arteriovenous malformation

The occurrence of a primary brain tumour in association with a cerebral arteriovenous malformation (AVM) is a recognized but rarely reported finding. A 56-year-old female presented following a single tonic clonic seizure. Radiological investigations revealed a left posterior frontal parafalcine meningioma and a left parietal AVM. Both were uneventfully resected. Whether there is a causal relationship is unproven, however, this case report might lend some support to this hypothesis given the relatively close proximity of the two lesions.
