Sudden death caused by myocardial tuberculosis: case report and review of the literature.
A 25-year-old fit man died suddenly while playing social soccer. Autopsy revealed an infiltrative lesion involving the left ventricle with overlying pericarditis. No other significant pathologic changes were observed. Histologic examination showed necrotizing granulomatous inflammation. No acid-fast bacilli were demonstrated in the pericardial fluid or on histologic examination. The presence of Mycobacterium tuberculosis DNA complex was confirmed by use of the ligase chain reaction technique. The differential diagnosis of myocardial tuberculosis includes sarcoidosis, rheumatic fever, rheumatoid arthritis, giant-cell-containing tumors, idiopathic (giant-cell) myocarditis, and bacterial infections such as tularemia and brucellosis. This case illustrates the protean manifestations of tuberculosis and highlights the use of molecular biologic techniques in arriving at a definitive diagnosis in cases of suspected tuberculosis.
