Abstract

Arisaema amurense is well-known as a poisonous plant. Its toxicity is probably due to calcium oxalate crystal, which provokes the painful oropharyngeal edema, hypersalivation, aphonia, oral ulceration, airway obstruction and hypocalcemia. Posterior reversible encephalopathy syndrome (PRES) is a disorder manifesting as neurological symptoms such as headache, encephalopathy, seizures and visual disturbance with reversible cerebral edema usually involving the bilateral posterior portion of the cerebral hemispheres. Here we report a case of PRES following ingestion of Arisaema amurense.
