Segmental dilatation of the jejunum resembling prenatal volvulus.

A case of prenatally diagnosed intestinal obstruction caused by segmental dilatation of the jejunum is presented. Routine ultrasound scan showed mild polyhydramnios, a dilated small bowel loop, and scoliosis. On repeat ultrasound scan a volvulus was suspected, which led to cesarean section and laparotomy of the newborn, revealing the underlying pathology. Segmental resection and end-to-end anastomosis were followed by an uneventful recovery. Segmental dilatation of the intestine should be considered as a cause of prenatally manifested intestinal obstruction. Concomitant anomalies are frequent and may be helpful in making the correct diagnosis. J Pediatr Surg 36:927-929.
