[Rhombencephalitis caused by Listeria monocytogenes].

We report the case of a 57-year-old man with Listeria rhombencephalitis. This had been ascertained by means of Listeria isolation from the cerebrospinal fluid. After an nonspecific prodromial period with nausea and headache, he developed fever, meningism, brain stem dysfunction and an organic psychosis. With early antibiotic therapy (ampicillin/gentamycin), it was possible to bring about a restitio ad integrum. Different brain-imaging methods (computed tomography, MRI, brain SPECT) in the acute and follow-up stages are discussed.
