Diagnosis of Anterior Inferior Cerebellar Artery Occlusion on Magnetic Resonance Angiography With Reference to Basiparallel Anatomic Scanning-Magnetic Resonance Imaging

—Case Report—

Abstract

A 67-year-old woman presented with symptomatic infarction in the territory of the anterior inferior cerebellar artery manifesting as vertigo, vomiting, and right facial weakness. Basiparallel anatomic scanning (BPAS) magnetic resonance (MR) imaging combined with MR angiography demonstrated the occluded anterior inferior cerebellar artery. Common anatomic variations and limited detection of the smaller branches on MR angiography sometimes hinder evaluation of the occluded artery. BPAS-MR imaging may have a supplementary role to MR angiography in the diagnosis of cerebellar artery occlusions.
