Fusiform aneurysm of the superior cerebellar artery: short review article.

Fusiform superior cerebellar artery (SCA) aneurysms are quite rare and only 9 cases have been reported in the literature. Fusiform aneurysms are a small group of cerebral aneurysms among the most difficult to treat. The therapeutic approaches in the limited number cited in the literature include surgery and endovascular occlusion. Surgical techniques which have been used are parent artery occlusion, trapping or body clipping of the bleeding site, and wrapping for fusiform aneurysms. Neurological condition, presence of collateral circulation, type and configuration of the aneurysm, and type of the dissection are important factors that predict the course of fusiform SCA aneurysms. We reviewed the literature on fusiform aneurysm of the SCA and report a further case treated surgically.
