Unusual presentation of brain abscess with uncommon organism in an immunocompetent person

Multiple brain abscesses due to Listeria monocytogenes was detected in a 55 year old immunocompetent person who had history of progressive weakness for last three months with difficulty in micturition and abnormal behavior for the same duration. The patient was diagnosed six months back as tubercular meningitis and was put on ATD (now in continuation phase). After being diagnosed with Listeria, the patient was put on antibiotic therapy and responded dramatically. The abscess, by virtue of being relatively large and superficially located, was drained surgically.
