A 73-year-old patient with hyperglycemia and rheumatoid arthritis presented with attacks of involuntary lingual movements that were associated with pain at the base of the tongue, often followed by aversion of head and eyes to the left with clonic contractions of the left corner of the mouth. Seizures could be induced by a combination of specific movement and somesthetic stimuli. Ictal EEG recording revealed a focal epileptiform discharge in the right centrofrontal area, thus confirming that the patient had lingual seizures, an extremely unusual manifestation.
