Pseudo-aneurysms associated with intracranial surgery: case report

We describe a patient in whom two non-symptomatic internal carotid artery and middle cerebral artery pseudo-aneurysms were diagnosed 1 year following the surgical removal of a clinoidal meningioma. The unusual number, location, form and evolution (actual follow up of 6 years) of these pseudo-aneurysms differentiate them from other vascular lesions associated with surgery. It is important to understand the mechanism of vascular injury in order to understand imaging features and the possible methods of treatment.
