Abstract

Neurological manifestations of internal carotid aretry (ICA) dissection include amaurosis fugax, cerebral ischemia, oculosympathetic paresis, and various cranial nerve palsies. Isolated hypoglossal nerve palsy is a rare manifestation of ICA dissection. A 55-year-old man developed dysarthria following sudden pain in the left retroauricular area. His tongue was paralysed on the left side. Magnetic resonance image and carotid angiogram showed characteristic features of left ICA dissection, which may be the most plausible cause of hypoglossal nerve palsy in this patient. Expanding hematoma of dissecting aneurysm of ICA seems to have compressed the nutrient artery of the hypoglossal nerve, although the possibility of direct compression of the hypoglossal nerve itself is not completely ruled out.
