Acute facial diplegia and hyperreflexia: A Guillain-Barré syndrome variant.

Two patients with acute facial diplegia and hyperreflexia are described. Both patients had serologic evidence of preceding Campylobacter jejuni infection and antiganglioside IgG antibodies as well as other laboratory and electrophysiologic findings suggesting Guillain-Barré syndrome (GBS). IV immunoglobulin produced recovery. Hyperreflexia does not necessarily exclude the diagnosis of a GBS variant. Antiganglioside antibodies can help with diagnosis in difficult cases.
