Temporary and Permanent Magnetic Resonance Imaging Findings in Status Epilepticus: Case Series

Abstract

Acute periictal imaging abnormalities caused by status epilepticus (SE) have been reported in recent years. In this study, periictal magnetic resonance imaging (MRI) changes, follow-up MRIs and electroencephalographic (EEG) features (e.g. periodic lateralized epileptiform discharges [PLEDs]) of 4 patients with SE were discussed. Diffusion restriction was the most common periictal MRI change (4/4) and it tended to resolve (3/4). Permanent MRI changes were seen in two patients. Patients with SE and periictal MRI changes mostly had PLEDs in EEG (3/4) and poor outcomes (3/4).
