Abstract
We report 2 cases of ruptured aneurysms of the posterior inferior cerebellar artery associated with an arteriovenous malformation (AVM). The aneurysm and AVM were simultaneously embolized with n-butyl cyanoacrylate. In one case both the aneurysm and the AVM were totally obliterated; in the other case the AVM was subsequently treated with radiosurgery. In both cases the aneurysms were successfully occluded. The effectiveness and limitations of this treatment are discussed.
