The rarity of such cases, coupled with the scarcity of comprehensive literature, makes the successful management of this case a source of valuable experience and novel insights for clinical practice.Case Presentation: A 32-year-old patient conceived following a clomiphene-induced ovulation regimen. Mid-pregnancy ultrasound indicated a twin pregnancy (one viable fetus, the other consistent with the appearance of a complete hydatidiform mole), and the patient chose to continue the pregnancy. At 36+4 weeks of gestation, the patient was admitted for pregnancy-induced hypertension and underwent a cesarean section, delivering a healthy female infant and simultaneously removing the molar tissue. Postoperative pathological examination confirmed a complete hydatidiform mole with invasive lesions, which progressed to an invasive hydatidiform mole. The patient underwent seven cycles of methotrexate combination chemotherapy, with a follow-up period of three years showing no recurrence, ensuring the health of both mother and child.Conclusion: Managing twin gestations involving a complete hydatidiform mole and a normal fetus necessitates a multidisciplinary approach, grounded in individualized assessment. The successful treatment of this case demonstrates that standardized diagnosis, close postoperative follow-up, and chemotherapy are crucial factors in improving maternal and fetal outcomes, offering significant clinical reference value.Keywords: complete hydatidiform mole, twin pregnancy, individualized management, chemotherapy, pregnancy-induced hypertension
