SummaryA 40 year old multiparous asymptomatic woman presented at 9+ weeks with a finding of rising serum beta-HCG over 3500 IU without ultrasonically detectable intra-uterine pregnancy. First diagnostic laparoscopy was performed on 3rd day of admission and found to be normal. Because of rising serum beta-HCG second laparoscopy was performed and it was converted to a laparotomy as a caesarean scar site pregnancy was suspected. Sub-total hysterectomy was performed in order to remove suspected caesarean scar molar pregnancy. Patient recovered completely with normal beta-HCG on 20th post day. Pieces of tissue obtained from between the anterior abdominal wall and the previous caesarean section scar revealed diagnosis of complete hydatidiform mole.Background: Implantation at the caesarian scar site can lead to first trimester miscarriages, placenta previa, placenta accreta or ectopic pregnancy. While caesarean scar site ectopic pregnancy is a rare occurrence; caesarian scar site molar pregnancy is extremely rare. We report this case to highlight the importance of high index of suspicion and proper monitoring in diagnosing this condition.
