title: Pulmonary tuberculosis accompanied by a transient increase in serum carcinoembryonic antigen level with tuberculous empyema drainage.
abstract: We present a case of pleural effusion with encapsulation that was observed in the right thorax of a patient. PCR analysis of the patient's pleural effusion showed positivity for Mycobacterium tuberculosis. After six months, his chest CT showed the development of niveau and pulmonary consolidation. We definitively diagnosed him as having chronic pulmonary tuberculosis with tuberculous empyema drainage. At the time of his hospital admission, his serum carcinoembryonic antigen (CEA) level was elevated. After we started treatment using antituberculosis drugs, the infiltration shadow in his lung fields disappeared, and the serum CEA level decreased. The results suggest that the serum CEA level reflects the extent of the development of pulmonary tuberculosis lesions.
