Morbidly adherent placenta is a spectrum of obstetric complication which is life threatening to both mother and fetus. Congenital uterine malformation is a rare cause of such a condition. Here we present a case report of placenta increta in bicornute, unscarred uterus. An 18 year old para1+1 presented in emergency with history of vaginal delivery of still birth baby followed by vaginal bleeding with retained placenta. Her Examination under anaesthesia and failed attempt of manual removal of the placenta performed in emergency followed by Doppler ultrasound showed a bicornuate uterus with possibility of placenta increta, later this diagnosis was confirmed on magnetic resonance imaging (MRI). Patient managed with injection methotrexate along with folinic acid followed by removal of placenta under general anesthesia, hence we preserved her fertility. The aim of this report is to emphasize the importance of this rare but a possible association of nonscar and malformed uterus with spectrum of abnormal placentation. Obstetrician should run a full set of investigations in such cases to prevent maternal and fetal mortality and morbidity.
