Abstract: This study aimed to analyze the diagnosis and treatment process of patients with hematogenous disseminated pulmonary tuberculosis after treatment with in vitro fertilization-embryo transfer (IVF-ET). We retrospectively analyzed the clinical data, including imaging and etiological data, the use of antimicrobials, metagenomic next-generation sequencing (mNGS) results, and the treatment process, of a patient who underwent IVF-ET due to an obstruction in the fallopian tube; after the treatment, she developed a persistent fever with shortness of breath and suffered a spontaneous abortion. Due to the failure of other treatment modalities, fiber optic bronchoscopy was performed, and the alveolar lavage fluid was obtained for mNGS. Tests for Mycobacterium tuberculosis  and rifampicin resistance (Xpert MTB/RIF) showed positive and negative results, respectively. Subsequently, anti-tuberculosis treatment with isoniazid, rifampicin, pyrazinamide, and ethambutol was administered. After the patient’s condition improved, she was transferred to a specialized tuberculosis hospital for further treatment, where she died one month later from multiple organ failure. From this case, we conclude that clinicians should remain highly vigilant for pulmonary infection with M. tuberculosis in pregnant women, particularly in patients treated with IVF-ET, and check for its presence as soon as possible.
