Abstract

Status epilepticus (SE) is one of the common neurological emergencies. Neuroimaging may detect structural lesions in the investigation of SE etiology. In addition, signal changes, which are usually transient and seldom permanent, can be detected in the cortex in the region where seizure activity starts or associated epileptogenic cortex and these magnetic resonance imaging (MRI) findings may be associated with neuronal damage. A seventeen years old male patient referred to emergency service with the diagnosis of SE. His seizure was controlled and in cranial MRI, in T2-weighted images and FLAIR (fluid-attenuated inversion recovery) sequences hyperintense signal activity was detected in right temporooccipital subcortical area in substantia alba , with contrast and edema around, and involving cortex. In control MRI, although these lesions did not completely disappear, they regressed markedly. In SE, in MRI completely reversible and rarely permanent lesions can be seen. The significance and cause of these lesions, which have atypical localizations and do not completely disappear even if they regress can be elucidated through further studies on the issue.
