Cerebrovascular complications are rare following viper bites. A 65-year-old man presented with loss of consciousness and developed haemiparesis following a viper bite. Coagulation parameters were severely deranged. MRI showed acute ischaemic infarction on the left side in the precentral and postcentral gyrus, hemipons and cerebellum. Troponin T was elevated and transient left bundle branch block was seen. The patient had a good outcome following treatment with Anti Snake Venom and supportive therapy. Possible mechanisms of infarction are discussed.
