Listeria pericarditis in a lymphoma patient: Case report and literature review

Abstract

We present a case of pericarditis with pericardial effusion secondary to Listeria monocytogenes. A 56-year-old man presented with signs of acute pericarditis, but with prior chronic lymphocytic leukemia treated with stem cell transplantation, chronic graft-versus-host disease, and a recent diagnosis of untreated diffuse large B-cell lymphoma. He developed cardiac tamponade requiring pericar-diocentesis. Blood and pericardial cultures grew Listeria monocytogenes. He responded to ampicillin but later died from gram-negative sepsis. A systematic review found 10 other published English-language cases of pericarditis caused by Listeria. The most common risk factors were cirrhosis and malignancy. Only three patients survived both the listeriosis and their underlying infections. Listeria monocytogenes is a rare and often fatal cause of pericarditis, typically occurring in immunocompromised patients. Cultures showing gram-positive bacilli in the context of pericarditis in an immunocompromised patient should prompt consideration of this rare cause.
