The cranial computed tomographic scan showed several large brain abscesses in the left parietal cortex and diffuse edema. The 2 largest abscesses were drained and 70 mL of a malodorous pus was evacuated. The abscess culture was positive for Citrobacter diversus. A therapeutic regimen of intravenous antibiotics (gentamicin sulfate, cefotaxime sodium, and metronidazole) and phenobarbital sodium was started. During the next 2 days, the abscesses were locally irrigated with a gentamicin solution. An electroencephalogram, performed the day after admission to the hospital, showed generalized slow background activity, without focal abnormalities or epileptic activity.
