Background: Body stalk anomaly was a rare, sporadic defect in the abdominal wall with the expulsion of the contents of the thoracoabdominal organs. Body stalk anomaly was reported in about one in 7,500 births within 10–14 weeks of gestation. Body stalk anomaly was a rare malformation with a prevalence of about 0.12 cases per 10,000 births (both live and stillbirth). Aim: To compare the antenatal and postnatal findings of body stalk anomaly. Case description: A 29-year-old multigravid patient was referred to our hospital due to a congenital anomaly. There were several findings on ultrasonography and magnetic resonance imaging (MRI), namely low-set ears, banana sign, neural tube defects, severe scoliosis, short umbilical cord, fetus attached to the placenta, abdominoschisis, thoracoschisis with some organs out, and defects in both legs. Hysterotomy was performed at 24 weeks of gestation. A male baby weighing 650 gm with a body length of 33 cm and head circumference of 24 cm was born. His Apgar score was 1/1/1 and survived for 30 minutes after birth. The postnatal examination of the baby, performed postmortem, confirmed the antenatal diagnosis. Synopsis: A case about a comparison between ultrasound and MRI prenatal screening with postoperative findings in the diagnosis of body stalk anomaly. Conclusion: Antenatal ultrasonography provided an accurate diagnosis of body stalk anomaly, and the results could be a consideration for detection of the defect earlier. Furthermore, it could help in patient counseling about poor outcomes in neonates and termination planning earlier to avoid other additional risks or even complications of delivery.
