Prenatal diagnosis and management of congenital volvulus

We present a case of a twin gestation in which one twin developed a complex abdominal mass and signs of small bowel obstruction. Following delivery, an exploratory laparotomy revealed a meconium pseudocyst and midgut volvulus. While the infant survived, a large portion of small bowel was atretic, resulting in short bowel syndrome. The prenatal diagnosis of volvulus is rare. When volvulus is present, the risk of bowel infarction is high, with variable perinatal outcome.
