Tuberculosis on regular hemodialysis--a case of pericardial tamponade.

The patient presented in this paper had been stable for 3 months after the induction of hemodialysis, when nausea, vomiting and hepatomegaly suddenly developed. A chest film revealed rush cardiomegaly, and massive pericardial effusion was demonstrated by echocardiography. One liter of hemorrhagic fluid was removed by pericardiocentesis and subsequent pericardial drainage under echocardiography. The patient received chemotherapy against pulmonary tuberculosis 30 years ago and calcification on chest film was apparent. Although sputum smear and pericardial effusion was negative for acid-fast organisms, combination therapy was initiated for suspected tuberculosis. The patient recovered completely and 2 months later it was demonstrated that cultures of sputum grew mycobacterium tuberculosis. Tuberculin skin test (PPD), which was negative 2 months previously, converted to positive. Tuberculosis must be considered as a potential cause of pericardial tamponade in patients on regular hemodialysis, and prompt therapy for both cardiac tamponade and the occult infection is warranted.
