[Abdominal epilepsy in the adult].

Abdominal epilepsy is a rare cause of abdominal pain. We report an adult patient with intermittent, paroxysmal epigastric abdominal pain, accompanied by nausea, vomiting, restlessness and anxiety. Physical examination was normal. Blood analysis disclosed only leucocytosis with neutrophilia. X ray examinations, ultrasound and CT abdominal scan, mesenteric arteriography and exploratory laparotomy did not show evidence of pathology. The electroencephalogram (EEG) showed bilateral theta slow activity during hyperventilation. We started treatment with carbamazepine and the patient remained asymptomatic for nine months. However he had a relapse because he did'nt take his medication regularly. At that time the serum levels of carbamazepine were low. The EEG showed bursts of diffuse paroxysmal acute waves. Once therapeutic serum levels of carbamazepine were achieved the pain disappeared. He has remained asymptomatic during the last twelve months, while taking his treatment regularly.
