Recurrent Pneumonia and Encephalitis due to Mycoplasma Pneumoniae

Abstract

Recurrent M. pneumoniae encephalitis in a young man is reported. The patient appeared not to be immunodeficient, and no direct evidence of invasion of his CNS by M. pneumoniae was obtained, despite the presence of a focal inflammatory brain lesion with a predominance of polymorphonuclear cells. Although the mechanism of CNS engagement in M. pneumoniae respiratory tract infarction is unknown, apparently certain individuals are somehow predisposed to such complications. CNS complications may occur even during a mild Mycoplasma respiratory tract infection. The radiological findings can mimic cerebral hemorrhage or abscess, necessitating neurosurgical exploration.
