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

Indian Journal of Radiology and Imaging, 2022
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.

A Case of Anterior Choroidal Artery Occlusion and Stroke Secondary to External Compression [PDF]

Case Reports in Neurology, 2021
The anterior choroidal artery (AChA) is a small artery commonly arising from the supraclinoid segment of the internal carotid artery (ICA). The significance of the AChA is related to its strategic supply to various important structures of the brain, such

Technical Approaches for Coil Embolization of Unruptured Small Anterior Choroidal Artery Aneurysms: A Focus on Anatomical Flow Preservation of the Anterior Choroidal Artery [PDF]

Neurointervention
The anterior choroidal artery (AChA) supplies the corticospinal tract related to the motor function of the upper and lower limbs. Aneurysms arising at the AChA are not common and exhibit various patterns of involvement of the AChA.
