Polyneuropathy complicating the diagnosis of normal pressure hydrocephalus: case report and review of literature.

Polyneuropathy is a rare association of normal pressure hydrocephalus (NPH) and may complicate the diagnosis of both diseases. We describe a patient with NPH who presented with acute polyneuropathy. The patient was initially thought to have Guillain-Barré disease (GBS). Early consideration of NPH in patients presenting with acute polyneuropathy could result in prompt diagnosis and treatment of NPH.
