[A case with mild subdural hematoma presenting with a transient cluster of convulsions--problems concerning differentiation from benign infantile convulsion and benign complex partial epilepsies in infancy].

A 1-month-old girl showed frequent partial seizures of sudden onset. Continuous spikes were observed in left central area during the ictal period, although interictal EEG showed neither epileptiform discharges nor focal signs. Optimal seizures control was obtained with intravenous administration of diazepam and subsequent oral administration of phenobarbital. She showed neither abnormal physical and neurological signs after seizures nor sequelae. CT examination on two days after the onset of seizures showed no obvious abnormal high density area. However, MRI examination on 10 days after the onset showed subdural hematoma in the left front-temporal area and right occipital area. Except for MRI findings, this case may be diagnosed as benign infantile convulsion or benign complex partial epilepsies in infancy. This case suggested that serial neuroradiological examinations were recommended for prospective studies about benign infantile convulsion and benign complex partial epilepsies in infancy.
