Complete Hydatidiform Mole and Co-Existing Live Fetus after Intracytoplasmic Sperm Injection: A Case Report and Literature Review.

Twin pregnancy with complete hydatidiform mole and co-existing fetus (CHMCF) is an uncommon obstetric entity and may occur after assisted reproductive technologies. These pregnancies are associated with severe complications for both mother and fetus and the management is challenging. We report a twin pregnancy after intracytoplasmic sperm injection (ICSI) treatment with CHMCF which delivered at 26 gestation weeks due to severe preeclampsia. The 625g neonate survived without any complication. The woman had persistent trophoblastic disease with lung metastasis and was treated with single agent methotrexate. We also present a brief review of the literature about the outcomes of CHMCF after ICSI. CHMCF may occur after ICSI treatment. Pregnancies with CHMCF are associated with severe complications however under close follow-up successful outcomes could be achieved in such pregnancies.
