A case of fatal progressive neuropathy: Delayed consequence of multiple bites of a non-venomous snake?

Neurotoxicity is a common feature of the acute syndrome of systemic snake envenomation. In this report a patient with delayed onset of neurological manifestations after multiple bites of a non-venomous snake is described. The neurological cascade consisted of segmental painful muscle spasms presented several days after the snake bites, which gradually subsided and within a month was followed by muscle weakness in the legs. The latter progressed to flaccid quadriplegia with additional respiratory and autonomic failure leading to death after total disease duration of 5.5 months. The possibility that this unique neurological syndrome of fatal progressive neuropathy could be caused by either tetanus or an immune reaction initiated by snakebites is discussed.
