Abdominal pregnancy is a very rare type of Ectopic pregnancy which is associated with high morbidity and mortality for both the mother and the fetus. It poses a lot of challenges both in the diagnosis and management, hence high index of suspicion is important in making prompt diagnosis in such situation. We report a case of abdominal pregnancy with a live baby at 33 weeks gestation. A 32 years old Nigerian woman, Gravida 3 par 2 + 0 (2 alive) was referred to our institution from a peripheral hospital on account of abdominal pain of 4 months duration. The patient had exploratory laparotomy for Ectopic pregnancy and had a negative exploratory laparotomy. However, the abdominal pain and distention persisted and she was referred to our centre. After examination and investigations, the diagnosis of abdominal pregnancy at 33 weeks was made. She received Dexamethasome for lungs maturation and subsequently had laparotomy and the outcome was a live male preterm baby with a birth weight of 1.7kg. The placenta was attached to the anterior wall of the uterus and omentum. The baby died after 24 hours due to repeated episodes of apnoea, the patient was discharged after a week.
