MR examination done within 24 hours of status epilepticus. Contiguous T2 images reveal swelling and increased T2 signal of the right hippocampus (black arrows). The left hippocampus (white arrows) shows normal morphology and signal pattern.

MR examination, done on the same day, revealed increased T2 signal and edema involving the right hippocampus (Figure 1) with no pathological contrast enhancement.
Follow-up MR examination done 7 months after status epilepticus. Coronal T2 and FLAIR images show volume loss (atrophy) and increased T2 signal of the right hippocampus (black arrows). The left hippocampus shows normal architecture, normal volume and signal pattern.

Images obtained around 7 months after the initial presentation showed signal changes and atrophy of the right hippocampus along with mild global parenchymal volume loss (Figure 2).
