A 75-year-old woman presented to the Tropical Diseases Hospital, Goiania, Brazil, with a two-day history of fever and chills followed by headache and vomiting over the last 24 hours. The cerebrospinal fluid (CSF) showed 270 leukocytes/mmc (30 percent neutrophils); 20 red cells/mmc; undetectable levels of glucose and 232 mg/dL of protein. The Gram stain revealed several Gram-positive cocci, and CSF culture yielded Streptococcus bovis. A colonoscopy showed diverticula in descendent and transverse colon. After a 14-day course of penicillin G, the patient was discharged in a good state of health, with only mild hearing impairment.
