ABSTRACT
We report a 1-year 6-month-old girl with ganglioglioma in the right medial temporal lobe who showed epileptic spasms in clusters. Spasms occasionally followed a dazed and fearful gaze. Interictal electroencephalography (EEG) showed diffuse bursts of slightly irregular high-voltage spikes and slow waves without hypsarrhythmia. The findings on ictal EEG, single-photon emission computed tomography, and F-18 fluorodeoxyglucose positron emission tomography indicated focus on the right medial temporal lobe. Ictal fast rhythmic activity analysis of scalp EEG by multiple band frequency analysis showed gamma rhythms at 65-80 Hz with a high spectral power around the tumor area. Epileptic spasms completely disappeared after tumor resection. These findings suggest that the cerebral cortex may be a source of epileptic spasms and indicate the possibility of usefulness of fast activity analysis in this condition.
