Tongue necrosis as an unusual presentation of carotid artery stenosis.

A 57-year-old man with premature coronary artery disease presented to the emergency department with left facial pain, numbness, and tongue swelling. The patient was found to have significant tongue necrosis, and subsequent arteriography demonstrated carotid bifurcation stenosis with embolization to the left lingual artery. The patient was successfully treated with debridement of his tongue and left carotid endarterectomy.
