ABSTRACT
A 17 year-old girl was suffering complex partial seizures, secondary generalized epilepsy and seizures manifested only by vomiting. The neurological, laboratory, radiological studies and the brain CT were normal. The EEG recording of an ictal vomiting showed bisynchronous spike-and-wave and sharp slow-wave discharges. An interictal paroxysmal focus of the right temporo-occipital region appeared at the EEG and a marked photoconvulsant effect was induced by light stimulation. The patient remained seizure-free for the last 4 years on carbamazepine therapy. The authors suggest the vomiting fits originate from the epileptic discharges on the Ammon's horn. The depths of the temporal lobe appear clearly involved in this type of seizures and the rolandic and pre-rolandic neighboring areas are attended too.
