Corpus callosum arteriovenous malformation with persistent trigeminal artery

Abstract

A 13-year-old boy presented with an intracerebral haematoma secondary to a large corpus callosal arteriovenous malformation (AVM) with an associated persistent trigeminal artery, and was treated with Gamma-Knife Radiosurgery for the AVM. This report discusses the embryological basis, radiological features and various classifications of this rare vascular anomaly.

Key words:

• Persistent trigeminal artery
