Anterior choroidal artery aneurysms could have different symptoms, and outcomes: a report of 3 cases treated endovascularly

Abstract

Anterior choroidal artery (AChoA) aneurysms are rare intracranial aneurysms, which are treated with endovascular techniques or surgical clipping procedures. AChoA aneurysm may have variable symptomatologies, clinical courses, and outcomes due to the eloquent territory of the artery. We have presented 3 cases of AChoA aneurysms, which differ from each other and literature by rare oculomotor nerve palsy, antiplatelet treatment complication and near-complete late resolution of the oculomotor nerve palsy. We have tried to share our AChoA case experiences to emphasize the importance of being flexible and adaptable in the diagnosis, treatment and follow up of this rare intracranial aneurysm type.
