- Abstract: A 16-year-old primigravida, at 33 weeks and 5 days age of gestation came in due to preterm labor. Sonographic examination revealed an incidental finding of a mass attached to the sacrococcygeal area. The mass has a cystic and solid component diagnosed as sacrococcygeal teratoma. Attached to the mass were two lower extremity structures identified as femurs with feet and was considered as an underdeveloped parasitic twin. A classical cesarean section was performed because of the advanced preterm labor, and a live female infant weighing 2500 g was delivered. The parasitic lower limbs, however, inadvertently detached during delivery. There was a high index of suspicion because of a larger fundic height of 37 cm compared to the age of gestation and the difficult palpation on Leopold's maneuver. Accuracy of ultrasound findings helped the obstetricians to a timely and prepared for delivery.
