Morganella morganii is a Gram-negative facultative anaerobic rod. It frequently causes urinary-tract and wound infections. We identify 4 M. morganii brain abscess cases previously reported in adults in the literature. This is the first case of multiple brain abscesses after mastoiditis secondary to chronic otitis media. The patient presented to an emergency service with fever, nausea, vomiting, headache, otalgia, and a tendency to sleep. Computerized tomography of the brain and temporal bone tomography scan demonstrated subdural abscesses in the frontal and parietal areas, parenchymal abscess in the temporal lobe, and mastoiditis. The abscesses were evacuated immediately with surgery and M. morganii was grown from the aspirate. The patient was treated with intravenous meropenem (3×2 g/d) and improved without neurologic sequelae.
