[A case of Enterococcus faecalis brain abscess in a patient with suprapharyngeal cancer].
A 55-year-old male was admitted to our hospital for the treatment of suspected brain abscess on March 18, 1989. The brain CT scan showed low density area with ring enhancement. After admission, both cefminox 2 g/day and clindamycin 500 mg/day were administered intravenously. On March 29, 1989, the patient developed cerebral herniation suddenly. Therefore emergency burr hole operation was done. Many gram-positive cocci were observed on gram-staining of the aspirated pus. Moreover neutrophils with phagocytosed gram-positive cocci were also observed. Culture of aspirated pus revealed colonies of gram-positive cocci which were subsequently identified as E. faecalis. Same species of bacteria were also isolated from fistula of right mastoid. From both findings of brain CT scan and data of MICs of E. faecalis, it may be suggested that direct infection developed from right mastoiditis to intracranial space. We experienced a severe case who developed cerebral herniation because of brain abscess due to E. faecalis which is an infrequent pathogen of brain abscess.
