title: Solitary supratentorial Listeria monocytogenes brain abscess in an immunocompromised patient.
abstract: We describe an 81-year-old man receiving azacitidine monotherapy for myelodysplastic syndrome who was improving from Listeria monocytogenes bacteremia after receiving antibiotic therapy during an earlier hospital admission. Shortly after discharge he developed new-onset seizure activity, with brain imaging on subsequent admissions demonstrating a posterior right frontal lobe mass. Specimen cultures after resection of the mass revealed this to be a cerebral abscess related to L. monocytogenes. Brain abscesses related to this organism are rare.
