[Myocardial infection by Mycobacterium: a case report].

Abstract

Mycobacterial infections of the cardiovascular system are rare and only a few reports provide detailed pathological information. This report presented a rare case of asymptomatic myocardial mycobacterial infection identified at autopsy. The patient died from pulmonary thromboembolism. The Myocardial mycobacterial lesions were found during the histological examination. Although myocardial tuberculosis was considered highly probable, real-time quantitative fluorescence PCR tests for Mycobacterium tuberculosis on paraffin-embedded heart and lung tissues were negative. This report discusses the predisposed populations, routes of dissemination, clinical manifestations, associations with cardiovascular events, and diagnosis and treatment of mycobacterium infections, with a focus on myocardial tuberculosis, to enhance clinicians' understanding of myocardial mycobacterium infections.
