Association of intracranial aneurysm and arteriovenous malformation.
In a series of 252 patients (47 with arteriovenous malformation, 205 with aneurysms), two patients had a coexisting intracranial aneurysm and an arteriovenous malformation. In one patient, the aneurysm was proximal to the main feeding arteries of the arteriovenous malformation. In the other patient, there was no anatomical relationship between the two lesions. These findings illustrate different views on the pathogenesis of the rare association of the two conditions.
