Anterior choroidal artery (AchA) is a branch of internal carotid artery. AchA infarcts are frequently presented by lacunar\udsyndromes. Hemiparesis is the most common presenting symptom. Horner syndrome and cranial nerve palsies are\udunusual findings for AChA infarcts. In case of presentation with these, etiopathogenesis should be reconsidered and reevaluated.\udA 42 year old man was admitted to our neurology clinic with right hemiparesis. He had Horner syndrom and\udhypoglossal nerve palsy. An acute AChA infarction was seen in cranial and diffusion-weighted magnetic resonance imaging\ud(MRI). As there was a suspicious sign of carotid dissection in extracranial MR angiography, digital substraction\udangiography was performed and dissection of left carotid artery in the subpetrosal region was observed. The patient was\uddiagnosed with left carotid artery dissection and was started on oral anticoagulan therapy. Presentation of an acute AChA\udinfarction due to the dissection of ICA is rarely observed. ICA dissections can sometimes be presented by Horner\udsyndrome and/or cranial nerve palsies. Especially in young stroke patients, dissection should be considered even if the\udpatient does not mention headache. \u
