- Abstract
- A brain abscess or empyema is a severe neurological infection with a high mortality rate. Rarely, Streptococcus species other than S. pneumoniae were responsible for brain abscesses or empyema. A few case series were reported in the literature. We present three cases of severe empyema and abscess induced by S. constellatus in three immunocompetent individuals. A 12-year-old girl presented with febrile meningeal syndrome. The CT scan showed a brain abscess and empyema associated with hemispheric edema. She underwent surgery for empyema evacuation and frontal lobectomy with a decompressive flap bone. A 52-year-old man presented with right-hemisphere heaviness, headache, and fever. Cerebral MRI showed an abscess of the left semi-oval center with signs of ventriculitis. He underwent neurosurgical drainage. A 14-year-old child admitted with right frontal swelling and osteitis in the context of fever. Cerebral MRI showed a right hemispherical subdural collection and thrombophlebitis of the superior sagittal sinus. The evolution was good only for the two children. Although S constellatus can cause serious infections in patients with underlying diseases and immunosuppression, physicians need to consider S constellatus infection in immunocompetent patients in the context of empyema and abscess. Early neurologic drainage and antibiotics must be installed on time to have a good outcome.
