Abstract

We report herein a patient with aphasic status epilepticus (ASE) who underwent serial brain magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI), perfusion imaging (PI), and magnetic resonance angiography (MRA) in the peri-ictal phase. The initial DWI revealed a high signal intensity in the left medial temporal area and PI demonstrated hyperperfusion in the left temporoparietal area. MRA revealed an increased flow signal in the ipsilateral intracranial arteries. PI signal changes had normalized by the follow-up MRI. The DWI, PI, MRA, and clinical manifestation of ASE are described herein. Key Words: Aphasic status epilepticus (ASE), Diffusion-weighted imaging (DWI), Perfusion imaging (PI)
