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].

MRI of the head was performed and no acute cerebral infarction, cerebral hemorrhage, and inflammatory changes were found (Figure 1).
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).

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).
