Abstract: Internal carotid artery (ICA) dissection is an important cause of stroke in young patients. Presentations may vary substantially and include headache, neck pain, Horner’s syndrome and, less commonly, lower cranial nerve palsies. Here, we outline a case of ICA dissection in a young adult patient who presented with an ipsilateral hypoglossal nerve palsy. CT angiography demonstrated typical findings, including the presence of a dissection flap, tapering arterial stenosis and double lumen sign. We consider the aetiology, investigation and management of ICA dissection, examine its radiological features and highlight the potential challenges in diagnosis.Summary: We present a case report of extracranial internal carotid artery dissection presenting with hypoglossal nerve palsy and consider the relevant clinical and radiological learning points.References: 1.
