Abstract

The most serious complications of the central nervous system that occur after venomous snake bite are intracranial hemorrhage and ischemic stroke.We present a rarely seen central nervous system complication, acute demyelinating encephalomyelitis, after a treated Deinagkistrodon's viper bite.On April 5, 2015, a 50-year-old male farmer was bitten on his right leg by a Deinagkistrodon's viper. The bite rendered the victim unconscious for 14 days, during which he was treated with tetanus toxoid and polyvalent antisnake venom. Acute demyelinating encephalomyelitis (ADEM) was suspected after magnetic resonance imaging of the brain. After a high dose of methylprednisolone was used as diagnostic treatment, the patient started recovering fast.ADEM is a rare complication after snake bite, and is triggered by venom or antivenin. Magnetic resonance imaging helps in the early diagnosis of ADEM, and high-dose corticosteroid therapy appears to be effective in ADEM after viper bite or antivenin management.
