<i>Listeria Monocytogenes</i> Brain Abscesses in a Patient with Disseminated Non-Small Cellular Lung Cancer: MRI Findings

Abstract

Brain abscesses caused by Listeria monocytogenes (LM) are very rare and carry a high mortality risk. We present a patient with disseminated non-small cellular lung cancer (NSCLC) and multiple unusual LM brain abscesses. These abscesses have multiple elongated peripherally enhancing lesions in a characteristic formation that is “worm or tramtrack-like” following the white matter fiber tracts.
