Abstract Background: Transient imaging abnormalities, including changes on diffusion-weighted imaging (DWI), maybe seen in status epilepticus. These abnormalities can be followed by hippocampal sclerosis. Case report: We report a 15-year-old lady with focal non convulsive status epilepticus (NCSE) and focal slowing on EEG. DWI exhibited abnormal hyperintense signals in bilateral temporal and insular cortices. After 3 weeks, MRI performed a localizated hippocampal atrophy. Conclusion: the MRI findings indicated vasogenic and cytotoxic edema during seizure activity and subsequent loss of brain parenchyma.
