An uncommon detection of Mycobacterium tuberculosis in pericardial effusion

: Pericardial tuberculosis is a specific pericarditis which is rarely reported in the absence of pulmonary tuberculosis. A case history is presented of a 74-year-old patient, immunocompromised as a result of kidney and liver cancer therapy. Mycobacterium tuberculosis was repeatedly recovered from pericardial effusion but not from other clinical specimens. Despite the early treatment of specific pericarditis, the patient died.
