Abstract

Distal thrombosed aneurysm of the superior cerebellar artery (SCA) is extremely rare and is often associated with cerebellar infarction or subarachnoid hemorrhage. We report herein on a case involving a patient with a ruptured thrombosed distal SCA aneurysm which was treated successfully through the endovascular approach.

Figure

• 

  Fig. 1 Brain computed tomography (A) shows subarachnoid hemorrhage and a round, hyperdense lesion in the right ambient cistern (suggestive of a thrombosed aneurysm). Diffusion-weighted magnetic resonance imaging (B) shows an acute infarction in the right cerebellum.

• 

  Fig. 2 A left vertebral angiogram shows a thrombosed distal SCA aneurysm. Anteroposterior (A) and lateral (B) view.

• 

  Fig. 3 A left vertebral angiogram after occlusion of the aneurysm and parent vessel with coils. Native anteroposterior (A), Anteroposterior (B) and lateral (C) view.

• 

  Fig. 4 Diffusion-weighted magnetic resonance image one week after treatment shows a multifocal acute infarction in the right cerebellum.
