Twin pregnancy with Hydatidiform Mole and Co-existent Live Fetus: Lessons Learnt

This is a case report of a twin pregnancy with one fetus and a coexistent mole diagnosed at 13 weeks. After thorough counseling, the pregnancy was continued as per the patient's desire. The pregnancy was closely monitored with serial S β hCG, ultrasound for fetal growth, size of molar sac, and theca lutein cysts, which gradually decreased in size during the second trimester of pregnancy. An emergency caesarean delivery was done at 36 weeks due to breech in early labour. A live baby weighing 1.8 kg was delivered in good condition. Her S β hCG reached normal levels at the end of three weeks, and she is now on post-molar surveillance. Though the general trend is to terminate pregnancy in twins with coexistent mole in anticipation of complications, under close surveillance, optimal outcomes can be achieved. Monitoring of S β hCG, serial ultrasound for fetal growth, size of molar component, and theca lutein cysts can help to predict good patient outcomes.
