A rare isolation of Parvimonas micra from cerebellar abscess in a patient with complex cyanotic heart disease.

Parvimonas micra is a gram-positive coccus which is an obligate anaerobe. It is a commensal in the oropharyngeal cavity and the gastrointestinal tract. The genus Parvimonas has only a single species, P. micra. Although there are several reports of infections due to P. micra involving various body sites, cases of brain abscess due to this organism have been under-reported in the literature. Here we present a rare case of cerebellar abscess caused by P. micra in a nine-year-old boy with complex cyanotic heart disease.
