BACKGROUND: Tuberculosis is a public health problem worldwide, and China is a high-burden country. Hematogenous disseminated pulmonary tuberculosis is one of the most serious forms of tuberculosis, and diagnosing hematogenous pulmonary tuberculosis is a challenge, even for the most experienced clinicians, who may also feel perplexed. We report a case of hematogenous disseminated tuberculosis involving multiple organs that was initially misdiagnosed as metastatic malignancy. The diagnosis was finally confirmed by metagenomic Next-Generation Sequencing (m-NGS) of peritoneal and pericardial effusions, which detected Mycobacterium tuberculosis complex.
METHODS: Appropriate laboratory tests, m-NGS, Chest and abdominal CT, Pericardiocentesis, and Peritoneal puncture.
RESULTS: Chest and abdominal CT showed diffuse nodules in both lungs, pericardial effusion, bilateral pleural effusion, and abdominal pelvic effusion. Tuberculosis bacillus antibody was negative, erythrocyte sedimentation rate increased to 42 mm/H, and the carcinoembryonic antigen (CEA) increased to 7.1 ng/mL, peritoneal effusion adenosine deaminase increased to 65.17 U/L, pericardial effusion adenosine deaminase increased to 142.39 U/L. m-NGS of pericardial effusion and peritoneal effusion detected 886,963 M. tuberculosis complex.
CONCLUSIONS: Miliary tuberculosis is a severe and rare form of tuberculosis. Delayed diagnosis may be the most important factor leading to death from miliary tuberculosis. We report a case where Mycobacterium tuberculosis was identified through mNGS of pericardial and peritoneal effusions, enabling rapid diagnosis of disseminated tuberculosis. This case provides a new approach for the rapid diagnosis of disseminated tuberculosis.
