A Successful Conservative Management of Twin Gestation of Complete Molar Gestation and Co-Existing Normal Fetus: A Case Report

Twin pregnancies consisting of one normal fetus and one complete mole are very rare. The main concerning risks associated with the continuation of such pregnancy are hyperthyroidism, theca lutein cysts, preeclampsia, and the development of GTD (gestational trophoblastic disease) spectrum (neoplasia) in the mother, which is due to high human chorionic gonadotropin (HCG) values, and intrauterine death and prematurity in the coexistent normal fetus. We report the successful outcome of conservative management in a healthy mother and baby. A 29-year-old patient was diagnosed with a complete mole and coexisting fetus in the 13th week of pregnancy. The risks of continuing with molar pregnancy were discussed in detail with the patient after informed consent to continue the pregnancy was obtained. With close monitoring, the pregnancy progressed, and she had spontaneous preterm labor and delivered an alive, healthy baby at 34 weeks. Post-delivery, the mother and child had no complications. Follow-up beta HCG dropped to less than 5 IU/mL at six weeks post-delivery. However, close follow-up was continued for the next six months, ensuring optimum health for the mother.
