title: Transient global amnesia: increased signal intensity in the right hippocampus on diffusion-weighted magnetic resonance imaging.
abstract: We report on a patient with pure transient global amnesia (TGA) whose magnetic resonance imaging (MRI) demonstrated a small region of increased signal intensity in the right hippocampus on diffusion-weighted imaging (DWI). DWI was sensitive and useful for evaluating the early stage of TGA and might help to explain the pathophysiology of TGA.
