We report the case of a 81-year-old, immunocompromised Patient, admitted to our hospital with new-onset headaches and word-finding difficulties. The MRI of the brain revealed a temporal mass on the left with marginal contrast-enhancement. During the next days Listeria monocytogenes grew in the bloodcultures so that the diagnosis of a brain-abscess caused by Listeria was established. ⋯ The MRI after therapy demonstrated no abscess persistence. Listeria mostly cause infections in the immunocompromised, elderly, newborn or pregnant host. Next to bacteraemia without a focus, CNS-invasion with meningitis, meningoencephalitis or less frequent abcess-formation (5-10%) is the most important manifestation.
