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