Transient Global Amnesia Secondary to Atherosclerotic Stenosis of Accessory Posterior Cerebral Artery

A 65-year-old woman was presented with a sudden onset of anterograde amnesia and iterative questioning after physical activity. Her past medical history included hypertension, diabetes, 2 symptomatic stroke events involving left temporal lobe infarction (Fig 1, A), and left basal ganglia infarction. There were no other positive neurological signs on this admission except for the previously right hemiparesis. At 3 days after onset, diffusion-weighted imaging (DWI) showed left hippocampal restricted diffusion foci (Fig 1, B).
