Posterior circulation stroke in a young male following snake bite.

Neurological deficits can occur following snake bite. It is usually due to intracerebral haemorrhage or subarachnoid bleed as a result of depletion of clotting factors. A healthy 14-years-old male developed bilateral ptosis and altered sensorium within 3 hours of snake bite. CT Brain revealed bilateral cerebellar and right occipital infarction with mass effect. Clotting time and bleeding time were normal. The possible mechanism for infarction in this patient is discussed.
