Reversible changes in echo planar perfusion- and diffusion-weighted MRI in status epilepticus

Neuroradiology. 2000 Feb;42(2):92-5. doi: 10.1007/s002340050021.

Abstract

Perfusion imaging (PI) demonstrated increased perfusion and diffusion-weighted imaging (DWI) showed high signal limited to the left temporoparietal cortex in a 68-year-old man with nonconvulsive status epilepticus. The EEG showed a slow delta-wave focus. The patient recovered and PI, DWI and EEG changes completely resolved.
