Elsberg Syndrome With Albuminocytologic Dissociation - A Guillain-Barré Syndrome Mimic or Guillain-Barré Syndrome Variant?

Introduction: Elsberg Syndrome is a presumed infectious lumbosacral radiculitis, with or without accompanying lumbar myelitis, that is often attributed to herpes simplex virus type 2 (HSV-2).

Case: A 58-year-old man presented with lower extremity anesthesia, ataxic gait, radiological evidence of radiculitis, and CSF albuminocytologic dissociation. Polymerase chain reaction testing of CSF confirmed HSV-2 infection.

Conclusion: A variety of presentations are reported within the scope of Elsberg Syndrome, potentially with distinct disease mechanisms. Delayed onset of neurological symptoms after resolution of rash and absence of pleocytosis raises the possibility that some patients meeting criteria for Elsberg Syndrome have a post-infectious immune-mediated neuropathy. We advise a lower threshold for PCR testing of herpes viruses in patients with acute neuropathy and albuminocytologic dissociation, particularly in cases with early sacral involvement.
