Posterior Reversible Encephalopathy Syndrome As A Rare Manifestation Of Vasculotoxic Snake Bite

Snake envenomation often leads to various neurological complications but the incidence of leuko-encephalopathy is quite rare. A 25-year-old male presented following a viperidae snake bite with progressive lower limb swelling. He was treated with anti-snake venom and hemodialysis but on the fifth day of hospitalization he experienced multiple episodes of generalised tonic clonic type of seizures. MRI brain revealed features of Posterior reversible encephalopathy syndrome (PRES). Treatment was mostly supportive and patient was discharged after resolution of clinical symptoms. A repeat MRI after two weeks suggested normal study suggesting radiological resolution. Hence, this case highlights PRES as a possible complication of snake bite.
