Miller Fisher syndrome: an uncommon acute neuropathy

The syndrome of ophthalmoplegia, ataxia, and areflexia was first described in 1956 by Miller Fisher. This syndrome has long been believed to be a variant of Guillain-Barré syndrome (GBS), mainly because of its areflexia, cerebrospinal fluid findings, and its postinfectious presentation. The case of an 11-year-old male with Miller Fisher syndrome (MFS) is described. MFS differs from GBS in several key clinical features and presents an extensive and challenging differential diagnosis. It is useful to recognize MFS as both a variant of GBS and a distinct entity with its own therapeutic considerations.
