Partial seizure: an unusual cause of recurrent vomiting

Partial seizure is a rare cause of nausea and vomiting. We report an adult patient with abdominal discomfort lasting 15 years accompanied by nausea and vomiting at least twice a week. On admission, physical examination and detailed laboratory tests were normal. Abdominal ultrasound examination, upper gastrointestinal endoscopy and CT scanning of the brain did not reveal any evidence of disease. Electroencephalography revealed bilateral synchronous sharp wave discharges and spike wave activities. The diagnosis of partial seizure was considered and the patient was administered sodium valproate. The patient's symptoms subsided and he has been asymptomatic for the past 20 months. We conclude that partial seizure should be considered in patients suffering from abdominal complaints who do not have any underlying gastrointestinal disorder.
