Background: Placental chorioangiomas are common benign tumors with an incidence of 0.6%. Case Report: A 23 year old primigravida was diagnosed to have a placental mass of about 4 cms chorioangioma during routine ultrasound at 22 weeks gestation. She was on regular follow up, at 31 weeks gestation the mass increased to 6.5 cms and the pregnancy was complicated by polyhydramnios. She needed urgent delivery for abruptio placenta. Conclusion: Though this is the common presentation of placenta chorioangioma, interventions like laser coagulation, alcoholic ablation might have helped to prolong the pregnancy a few more weeks.
