A case report of cervical pregnancy after in vitro fertilization complicated by tuberculosis and a literature review

Although female genital tuberculosis may lead to infertility, pregnancy is still possible, especially through in vitro fertilization (IVF). In this eventuality, even latent tuberculosis (TB) infection is prone to reactivate. Because some of the symptoms of TB overlap with those of pregnancy, diagnosis and treatment may be delayed. We report the case of a 30-year-old infertile woman with repeated genital tuberculosis (GTB) who underwent two laparoscopic surgeries and anti-TB treatments. The woman conceived through IVF and, unfortunately, a cervical pregnancy was diagnosed, together with a third recurrence of GTB. When the condition became stable after anti-TB treatment, the pregnancy was terminated using oral mifepristone in combination with an ultrasound-guided local injection of methotrexate. The gestational sac was expelled 4 days later with minimal blood loss. In view of the reciprocal influence and interconnection between IVF, pregnancy, and TB, we conducted a literature review to provide valuable information for early diagnosis and treatment, as well as for routine screening before IVF of TB in infertile patients.
