Intestinal obstruction due to congenital intestinal malrotation is usually diagnosed in neonates but may, in rare cases, occur during pregnancy. The absence of specific symptoms in combination with its low incidence makes timely detection of intestinal malrotation-related obstruction difficult in expectant mothers. We present a rare case of a 23-year-old woman with a twin pregnancy following in vitro fertilization-embryo transfer (IVF-ET) who presented with symptoms of intestinal obstruction at 22+4 weeks of gestation. This diagnosis was not confirmed by imaging and the patient was managed conservatively. Following caesarean section, she gave birth to two healthy full-term infants. During the operation, malposition of the bowel and the typical Ladd's band confirmed intestinal malrotation. This is the first report of a congential malrotation complicating a multiple pregnancy, and highlights that malrotation without volvulus can be managed conservatively.
