Background:
Molar pregnancy with a coexisting live fetus is a rare occurrence. We report the only known case with a surviving coexistent fetus after gamete intrafallopian transfer (GIFT).
Case:
After GIFT, a 28-year-old primary infertility patient was diagnosed as having a complete hydatidiform mole coexisting with a live fetus at 13 weeks of gestation. At 36 weeks of gestation, a cesarean section was performed due to elevated serum human chorionic gonadotropin (hCG) levels, and a male infant with a normal appearance and weighing 2,688 g was delivered.
Conclusion:
If the patient desires to try to carry the fetus to viability after counseling on the possible associated risks of malignancy, it is possible to achieve fetal viability if (1) there is decline in the serum hCG level after it peaks before the second trimester, (2) ultrasound reveals degeneration of the molar part, and (3) there are no complications of pregnancy.
