PURPOSE: To report the first documented case of an enlarged hypoglossal branch of the ascending pharyngeal artery (APA) traversing the hypoglossal canal and continuing to the anterior inferior cerebellar artery (AICA).
METHODS: Magnetic resonance imaging (MRI), including extracranial and intracranial magnetic resonance angiography (MRA), was performed for the evaluation of suspected cerebrovascular disease in a 58-year-old man presenting with acute-onset right hemianopsia. The examinations were performed using a 3-Tesla scanner, and intracranial MRA was performed using a standard 3-dimensional time-of-flight technique.
RESULTS: MRA demonstrated an enlarged right APA entering the hypoglossal canal and continuing to the AICA. The right vertebral artery was hypoplastic and continued to the posterior inferior cerebellar artery.
CONCLUSION: We report the first documented case of continuity between the APA traversing the hypoglossal canal and the AICA. A meticulous review of MRA source images and the creation of maximum-intensity-projection and partial volume-rendering images are useful for the reliable recognition of this variation.
