Images of a 60-year-old woman (patient 7) with simple partial status epilepticus sustained for 5 days.

A, Ictal T2-weighted images show extensive swelling and increased signal intensity of the left hippocampus (left) and diffuse swelling with increased signal intensity at the cortical gray matter and subcortical white matter of the adjacent left temporal lobe (right).

B, Ictal diffusion-weighted images show increased signal intensity and swelling at the left hippocampus (left, arrows) and at the uncus (right, arrowhead), parahippocampal gyrus (right, black arrow), and inferior temporal gyrus (right, white arrow).

C, ADC maps show a 19% decrease of the mean ADC at the left hippocampus (left, arrow) and a 2% to 5% increase of the mean ADC at the subcortical white matter of the uncus, parahippocampal gyrus, and inferior temporal gyrus (right).

D, Follow-up T2-weighted images obtained 4 months after the onset of seizure show the resolution of the marked swelling of the left hippocampus and partial resolution of the increased signal intensity of the left hippocampus (left). A tumor was revealed, which was diagnosed as glioblastoma multiforme at the left anterior temporal lobe (right).
