Muscle & nerve

A 49-year-old woman developed acute left facial, hypoglossal, and phrenic nerve palsies, as well as dysphagia and weakness in the neck and arms. Electrophysiologic studies showed an acute motor axonal neuropathy. ⋯ Intravenous immunoglobulin treatment resulted in good clinical recovery. The present report indicates that the cranial and phrenic nerves may be affected unilaterally in Guillain-Barré syndrome, and that there is clinical variability in the axonal subtype of this syndrome.
