Cranial neuropathy, myeloradiculopathy, and myositis: complications of Mycoplasma pneumoniae infection.

Polymyositis, transverse myelitis, ascending polyneuritis, bilateral optic neuritis, and hearing loss developed in a patient with high complement-fixing antibody titers to Mycoplasma pneumoniae. Each of her three children had primary atypical pneumonia with isolation of the organism. The neurologic disturbance is thought to represent a postinfectious complication of M pneumoniae infection.
