Clinical Characteristics of Distal Aneurysms of the Superior Cerebellar Artery

Case Report and Review of the Literatures

Abstract

We report a case of a 71-year-old man who presented a subarachnoid hemorrhage (WFNS grade 1) due to rupture of an aneurysm arising from the hemispheric branch of the superior cerebellar artery (SCA). On the 28th day after admission, the aneurysm was successfully clipped through the infratentorial supracerebellar approach in a Concord position. The patient was discharged with slight cerebellar ataxia 1 month after surgery. We discuss the clinical characteristics of distal SCA aneurysm with a review of literature.
