Due to lack of improvement in clinical status and EEG findings of PLEDs, a brain MRI was repeated with coronal sections and revealed T2 hyperintensity with mild swelling of the left hippocampus with abnormal contrast enhancement (Figure 1).
Follow-up MRI brain with contrast, 1 month after discharge, showing improved swelling of the left hippocampus with mild atrophy and volume loss on (a) FLAIR sequence coronal section and (b) T2-weighted coronal section.
