KUSTER, Gustavo Wruck et al. Hippocampal sclerosis and status epilepticus: cause or consequence? A MRI study. Arq. Neuro-Psiquiatr. [online]. 2007, vol.65, n.4b, pp. 1101-1104. ISSN 0004-282X.  http://dx.doi.org/10.1590/S0004-282X2007000700002.

BACKGROUND: Transient imaging abnormalities, including changes on diffusion-weighted imaging (DWI), may be 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.
