Right anterior inferior cerebellar artery supplied by the hypoglossal branch of the ascending pharyngeal artery diagnosed by magnetic resonance angiography

Puntos clave

• Findings reveal an unusual vascular source for the right anterior inferior cerebellar artery, indicating a unique anatomical variation.
• The magnetic resonance angiography (MRA) identified the hypoglossal branch as a supplier of the cerebellar artery, highlighting its role in cerebrovascular anatomy.
• Assessment used MRA to visualize the vascular anatomy, revealing the ascending pharyngeal artery's role in supplying the posterior fossa structures.
• Anatomic variations like this emphasize the importance of thorough imaging techniques in understanding vascular configurations.
