ABSTRACT
Meningiomas associated with intracranial aneurysms are very rare. The co-existence of both lesions is not only a diagnostic challenge but also has important therapeutic implications. We analyzed our experience of five such patients, the second largest group in the literature. All the lesions were successfully managed surgically. All the patients were female. The location of the meningioma was clinoidal (2), planum sphenoidale (1), petroclival (1) and pterional (1). Three patients had posterior communicating (PCOM) artery aneurysm associated with meningioma. The other aneurysms were internal carotid artery (ICA) and anterior communicating artery (ACOM). One patient with pterional meningioma had an anomalous meningeal artery arising from the right ophthalmic artery. In three patients both lesions underwent treatment at the same sitting. In two patients meningioma underwent excision first followed by aneurysm clipping. From our experience the incidence of meningiomas associated with aneurysms was 1.1%, which is not higher than the incidence of aneurysms in the general population.
