Abstract

A 64-year-old woman presented with headache and visual disturbance which occurred 10 minutes after bee venom acupuncture. She was normotensive. Her pupils were isocoric and normally reflexive but she could precept only lights just in front of her eyes. The brain MRI showed vasogenic edema in the cerebellum and occipitotemporoparietal areas. She fully recovered 2 days later. The brain MRI taken after 7 days revealed remarkable improvement. This case suggests that bee venom might cause posterior reversible encephalopathy syndrome.
