[An unusual presentation of tuberculosis].
A 67-year-old male was hospitalized because of nonspecific symptoms and bilateral pleural effusions. He gave no history of cough, dyspnea or thoracic pain. The blood counts showed moderate anemia and high-grade lymphopenia. The tuberculin test and the anergy-panel were both negative. Testing for HIV was negative. Analysis of pleural fluid showed an exudate with 47% lymphocytes and absence of acid-fast bacilli on Ziehl-Neelsen smear. On histologic examination, the pleural tissue showed no evidence of granuloma. However, cultures for mycobacteria of pleural tissue yielded M. tuberculosis. In this case of pleural tuberculosis, leading symptoms were absent and the tuberculin test was negative in the presence of active tuberculosis. In addition, the cells in the pleural effusion were not predominantly lymphocytic. Patients presenting with unclear effusion should undergo extensive investigations, including a tuberculin test, and anergy panel, pleural fluid cultures, and pleural biopsy with cultures for microorganisms, with the object of establishing or ruling out pleural tuberculosis.
