Ischemic vascular accident revealing hypoplasia of the internal carotid artery in a narrowed bony canal: A case report

Abstract

Hypoplasia of the internal carotid artery is a rare congenital abnormality that can present with an ischemic stroke or transient ischemic attacks. We present the case of a 17-year-old male who presented with right hemiparesis and dysarthria. The imaging revealed hypoplasia of the left internal carotid artery and narrowing of the left carotid duct. The patient was managed conservatively. This case highlights the importance of considering ICA hypoplasia as a cause of ischemic stroke in patients with a narrowed osseous canal. Early diagnosis and management can help prevent recurrent strokes.
