We report a patient who showed vasogenic edema on MRI in association with partial status epilepticus. The patient, for a month, experienced clonic movements of the right arm and leg. As the amplitude and frequency of the clonic movements increased, resulting in epilepsia partialis continua, MRI showed characteristic vasogenic edema features;normal or decreased signal on diffusion-weighted imaging, and increased apparent diffusion coefficient value in the left parasagittal frontal region with strong leptomeningeal enhancement. This region was corresponded to the leg motor area, which was correlated with the degree of hypemetabolism of ictal FDG-PET findings. Considering limited progression of the seizure activity and focal slow waves on EEG, time-locked by clonic jerks, which might result from synaptic inhibition, this case suggests that vasogenic edema may be associated with a lower intensity of the seizure activity compared with cytotoxic edema noted in most of the reported patients.
