Early Detection by Ultrasound of Partial Hydatidiform Mole With a Coexistent Live Fetus.

Introduction: Twin pregnancy with hydatidiform mole and coexistent live fetus is a rare condition with severe maternal and fetal complications such as preeclampsia, vaginal bleeding, persistent gestational trophoblastic tumor, and fetal death.

Case Presentation: We report a case of a twin pregnancy with histopathologically proven hydatidiform mole and a coexistent live fetus in a 30-year-old Indian woman diagnosed by first trimester ultrasound.

Discussion: Our case emphasizes the role of ultrasound in diagnosing this condition in early pregnancy. A succinct overview of etiological mechanisms, possible complications, and clinical management is provided.

Conclusion: Ultrasound is an effective diagnostic tool to diagnose hydatidiform mole with coexistent live fetus. Early diagnosis of this condition is important for risk stratification and facilitates an informed decision by the patient whether to terminate the pregnancy or to continue until full term with close monitoring after delivery.
