We report one case of extrapulmonary mycobacterial infection, in the absence of HIV infection, singular by a clinical presentation simulating a tumor, associating a bulky intrahepatic mass, an abscess of the psoas, multiple intracerebral lesions, and an obstructive intracardiac mass of the right ventricle, which required a surgical resection. We comment the type of the mycobacterium involved and the hepatic and cardiac localisations, since macronodular hepatic abscesses are rare, and cardiac abcesses, exceptional.
