Management of breech presentation with a large pelvic hydatid cyst in late pregnancy in Tibet: a case report

BACKGROUND: Hydatid cystic disease (HCD) is primarily a disease of sheep and cattle. Human beings are accidental hosts. It is prevalent in the Tibet Autonomous Region (TAR) of China. In pregnancy, it can cause many complications. CASE PRESENTATION: We present a multigravida with breech presentation at 37 weeks of pregnancy in whom a large pelvic hydatid cyst and multiple hepatic hydatids were diagnosed by ultrasonography. The large pelvic hydatid cyst was drained through the posterior fornix under the guidance of ultrasound, and an external cephalic version was performed. A healthy baby was delivered vaginally with head presentation at term. CONCLUSION: HCD during pregnancy presents with management difficulty. It is important to formulate individualized treatment plans according to the actual situation of the patient and the local level of treatment.
