Common trunk anomaly of the anterior and posterior inferior cerebellar artery in hemifacial spasm
BackgroundThe common trunk anomaly of the anterior and posterior inferior cerebellar artery (APC) is a variant artery that causes a hemifacial spasm...

Ruptured aneurysm arising at anterior spinal artery as the collateral circulation with bulbar artery supply to posterior inferior cerebellar artery treated by proximal occlusion and occipital artery-posterior inferior cerebellar artery bypass: a case report and literature review
The cases of aneurysms arising from collateral vessels that supply the posterior inferior cerebellar artery (PICA) are so exceptionally rare that...

Bilateral duplicated hypoplastic superior cerebellar arteries one of which originates from a full-type fetal posterior cerebral artery
PurposeThe association of bilateral duplication of the superior cerebellar artery with an origin from the posterior cerebral artery is rare but of...

Medial-type persistent trigeminal artery and ipsilateral posterior communicating artery supplying bilateral posterior cerebral arteries combined with an aberrant right subclavian artery and bicarotid trunk
PurposeTo describe a case of a medial-type persistent trigeminal artery (PTA) associated with multiple arterial variations.
MethodsA 34-year-old...
