Myocarditis and pericarditis with tamponade associated with disseminated tuberculosis.
Tuberculous involvement of the myocardium is relatively rare. Tuberculous pericarditis with tamponade and myocarditis in a young woman with no evidence of immunosuppression and disseminated tuberculosis is described. Three distinct forms of myocardial involvement are recognized: nodular tubercles (tuberculomas) of the myocardium; miliary tubercles of the myocardium; and an uncommon diffuse infiltrative type. The myocardium is involved by a hematogenous route, by lymphatic spread or contiguously from the pericardium. The diagnosis can be made by endomyocardial biopsy if clinical suspicion is strong and echocardiographic findings are suggestive. Antituberculosis drugs may be curative. With an increasing prevalence of tuberculosis, the possibility of potentially lethal myocardial tuberculosis is important to consider.
