[Mycoplasma pneumoniae meningoencephalitis in a young adult].

Mycoplasma pneumoniae infections have extrapulmonary complications that involve the nervous system. The neurologic manifestations are diverse. Although the prognosis is usually favorable, the patients can undergo severe permanent sequelae. We present a young female adult with acute meningoencephalitis as a complication of a lower respiratory infection, which followed a benign course without neurologic sequelae.
