Relapsing inflammatory neuropathy with normal peripheral nerve conduction studies – a paradoxical phenomenon in two patients

Abstract

The diagnosis of Guillain Barre Syndrome and Chronic Inflammatory Demyelinating Polyneuropathy depends on an appropriate history, examination, CSF cyto-protein dissociation and abnormal peripheral nerve conduction studies (PNCS). We present two cases suggestive of GBS but with repeatedly normal PNCS, a paradoxical phenomenon.
