case_images: MRI of the brain revealed change after removal of pituitary tumor and no acute cerebral infarction, cerebral hemorrhage, and inflammatory changes were found on T1 and T2 sequences [T1, T1-Weighted Magnetic Resonance Imaging; T2, T2-Weighted Magnetic Resonance Imaging (A) T1, (B) T2].

case_images: MRI of the head was performed and no acute cerebral infarction, cerebral hemorrhage, and inflammatory changes were found (Figure 1).
case_images: Electroencephalogram recorded. EEG demonstrates delta and theta waves in each lead as background, mingled with sharp waves, spike waves, sharp-slow waves (A). EEG shows a large number of sharp waves, spike waves, sharp-slow waves, spike-slow waves in the bilateral frontal pole, frontal and anterior temporal areas, paroxysmal or continuous, sometimes accompanied by evolution trend (B-D) (paper speed: 30 mm/s, high-frequency filter (HF): 30 Hz, low-frequency filter (LF): 0.53 Hz, notchfilers: 50 Hz, sensitivity:7 muv/mm. EEG A provided EEG background and the EEG B showed epileptic discharges).

case_images: A 24-h electroencephalogram (EEG) revealed sharp waves, spike waves, sharp-slow waves, spike-slow waves in the bilateral frontal region on a continuous slow-wave background with a trend of evolution, and the EEG also recorded paroxysmal electrical activities in this region (Figure 2).
