Hyperplastic Anterior Choroidal Artery—A Rare Variant Detected on MR Angiography

Abstract

Introduction The anterior choroidal artery is a branch of the terminal internal carotid artery (ICA) that is often an incidentally detected anomaly. The hyperplastic variant has been linked with an increased risk of aneurysms. We explore the role of magnetic resonance (MR) angiography in the detection of this variant and its impact of presentation of patients.
