title: Listeria monocytogenes: brain abscess or meningoencephalitis?
abstract: A brain abscess caused by Listeria monocytogenes developed in an immunosuppressed renal transplant patient. Meningitis and meningoencephalitis from this organism were encountered in three other renal transplant recipients at this medical center during the past 4 years. Focal neurologic deficits occurred in patients with either Listeria abscess or meningoencephalitis. Computerized tomography was a rapid aid to the diagnosis of abscess. Immunosuppression has increased the incidence of central nervous system Listeria infections, but ampicillin still provides effective treatment, even when immunosuppressive therapy is continued. Limited experience with Listeria brain abscess suggests that surgical intervention improves the prognosis.
