title: [A case of acute disseminated encephalomyelitis accompanying Mycoplasma pneumoniae infection].
abstract: We report a 30-year-old man with acute disseminated encephalomyelitis (ADEM) accompanying Mycoplasma pneumoniae (M. pneumoniae) infection. He was admitted to our hospital because of headache, disturbed behavior, and unconsciousness following an upper respiratory tract infection on December 19, 1996. On admission, he was febrile (37.3 degrees C) and showed hypersomnia and neck stiffness. There were scattered rhonchi in both lungs. Cerebrospinal fluid (CSF) contained 19 white cells; the protein was 20 mg/dl and glucose 71 mg/dl (blood glucose 170 mg/dl); no organisms were seen or cultured. Cranial MRI showed multiple T 2-weighted hyperintense in the periventricular region of the cerebral white matter. M. pneumoniae antibody titer in serum was remarkably elevated. ADEM related to M. pneumoniae was suspected. Although intravenous methylprednisolone, piperacillin and clindamycin were administered, there was no subsequent improvement in the symptoms. Further MRI scan revealed extension of the inflammatory lesion. He had both pneumonia and he required mechanical ventilation. Since the end of the critical period, he has been in an akinetic mutism. We conclude that M. pneumoniae has to be considered as a possible cause of ADEM with severe respiratory symptoms.
