Post Ictal Edema-DWI
MR
signal changes following seizure or status epilepticus are transient increase
of signal intensity and swelling at the cortical gray matter, subcortical white
matter, or hippocampus on peri-ictal T2-weighted and diffusion-weighted images.
These findings reflect transient cytotoxic and vasogenic edema induced by
seizure. This 11 year old patient has a calcified granuloma in the
posterior parietal region and this MRI was done immediately following seizure.
