Abstract

A 38-year-old man had postictal global aphasia after generalized tonic-clonic seizure, but recovered within 1 day. There was a focal increase in the signal intensity of the left frontoparietal sulci on fluid-attenuated inversion recovery magnetic resonance (MR) sequence 6 hours after the seizure, which disappeared 1 month later. The transient seizure-induced MR hyperintensity was possibly caused by ictal or postictal hyperemia and breakdown of the blood-brain barrier. This report aims to increase awareness of this condition and avoid unnecessary management.
