  • Abstract
  • Look Inside

We report a patient who presented with complex visual hallucinations in the right hemianopic field following an infarction in the left occipitotemporal base.

A 73-year-old right-handed woman developed right homonymous hemianopia. A week after its onset, she noticed a strange man with glasses, or a man wearing a gray hat and a black coat standing in the defective visual field. Such visual images later included a nurse, a large hand extending fromthe right side to the center, and many pieces of cloth descending from the roof. Most of these objects were unfamiliar to her, but may have been related to previous experiences.
