Listeria monocytogenes brain abscess in an immunocompromised patient: a case report

ABSTRACT

Listeria monocytogenes is a facultative intracellular gram-positive bacillus which usually infects immunocompromised patients, though it can infrequently infect immunocompetent individuals, neonates and pregnant women as well. Neurological manifestations include meningitis and cerebritis. Brain Abscess is an extremely rare presentation with approximately 80 reported cases. Authors report a patient with a brain abscess identified on an MRI scan with positive blood culture for Listeria monocytogenes. Patient was managed conservatively with intravenous followed by oral antibiotics with resolution of the abscess.
