title: Ruptured dissecting anterior inferior cerebellar artery aneurysm--case report.
abstract: A 39-year-old woman presented with a rare dissecting aneurysm of the proximal anterior inferior cerebellar artery (AICA). She presented with sudden onset of headache and vomiting, and subsequently became comatose with acute respiratory distress syndrome. Computed tomography showed subarachnoid hemorrhage and ventricular dilation. Left vertebral angiography identified a fusiform aneurysm at the proximal portion of the left AICA. The patient underwent endovascular treatment using Guglielmi detachable coils. The aneurysm was completely embolized. Computed tomography detected no infarcted areas in the regions supplied by the AICA. She was discharged without neurological deficits.
