Histopathologically Proven Poliomyelitis with Quadriplegia and Loss of Brainstem Function Due to West Nile Virus Infection

Abstract
Recent electrophysiological and histopathological reports point to motor neurons in the anterior horn of the spinal cord and the brainstem as targets of severe West Nile virus (WNV) infection. We report histopathological confirmation of this poliomyelitis-like syndrome in a patient with WNV infection in Massachusetts.
