EEG (longitudinal montage) showing a seizure at onset (A) and 30 s later (B). (A) Rhythmic theta activity, mainly in the left temporal region. (B) Rhythmic delta and sharp waves in the left hemisphere. Sensitivity, 10 microV; time constant: 0.3 s; high filter, 30 Hz; Notch filter, 60 Hz; 10 s/page.

EEG disclosed recurrent seizures, and the NCSE was terminated with midazolan and phenytoin (Figure 1).
T1- (right) and T2- (left) weighted magnetic resonance imaging images (coronal slices). (A) Increased left hippocampal volume with increased T2 and decreased T1 signals. (B) Reduced left hippocampal volume without signal changes.

MRI showed increased left hippocampal volume with hyperintensity on T2-weighted and FLAIR sequences (Figure 2A). A follow-up MRI 3 months after discharge showed reduction of the left hippocampus with enlargement of the left ventricle temporal horn (Figure 2B).
