Surgical resection of cavernous angioma located within eloquent brain areas: international survey of the practical management among 19 specialized centers


Cavernous angioma (CA) is an uncommon neurovascular brain lesion with a prevalence ranging up to 0.9% in the general population [1,2]. Cavernous angioma can be revealed by headaches, neurological and/or cognitive deficits related to an hemorrhagic event (up to 25%), by epileptic seizures (up to 25%), or discovered incidentally on MR examination performed for another reason (up to 50%) [1,3,4]. Epileptic seizures are common events during the natural course of CA and may be drug-resistant. The high likelihood of developing epilepsy after a first seizure, in the presence of CA (5-year risk of epilepsy, 94%), requires antiepileptic drug therapy [3].
