Meningoencephalitis and myocarditis due to mycoplasma pneumoniae in a 12-year-old boy

A 12-year-old boy presented with coma and cardiac arrhytmia after initial symptoms of a flulike febrile infection and otitis media. Titers against mycoplasma pneumoniae were significantly increased in serum. Detection of mycoplasma pneumoniae could not be found by PCR in a liquor sample. The patient had rapid and complete recovery over several days. This case,report demonstrates a well documented course of an mycoplasma-pneumoniae infection resulting in both coma and cardiac arrhytmia. It furthermore exemplifies that coma can result from acute infection with mycoplasma pneumoniae in the absence of an inflammatory cerebrospinal fluid response.
