Mycoplasma hominis brain abscess presenting after a head trauma: a case report

INTRODUCTION: Mycoplasma hominis brain abscess is a rare occurrence, and treatment is not well defined. The mechanism by which M. hominis infects sites outside the genitourinary tract, including the central nervous system, is unclear. CASE PRESENTATION: We report the case of a 40-year-old Somali man who sustained a traumatic brain injury that required initial neurosurgical hematoma evacuation and that subsequently was complicated by a hospital-acquired M. hominis brain abscess. Our patient was successfully treated with neurosurgical debridement and an antibiotic course of intravenous doxycycline. CONCLUSIONS: Head trauma or neurosurgical procedures or both might be a predisposing factor for this type of infection.
