Multiple cranial neuropathy associated with herpes simplex virus infection and anti-GM2 immunoglobulin M antibodies.

Antiganglioside antibodies can appear after several acute infections and are often associated with various clinical patterns of Guillain-Barré syndrome. Thus, for example, cytomegalovirus infection has been associated with anti-GM2 antibodies and Guillain-Barré syndrome variants with severe sensory loss and cranial nerve involvement. We report on a patient who developed multiple cranial neuropathy associated with herpes simplex virus infection and anti-GM2 immunoglobulin M antibodies.
