Delayed presentation of familial intestinal malrotation with volvulus in two adult siblings

摘要

Intestinal malrotation is an uncommon cause of abdominal pain and normally presents during infancy. Familial cases of malrotation are extremely rare in the absence of other congenital malformations. We present the case of a 22-year-old woman with undiagnosed chronic abdominal pain and her previously well 16-year-old brother who presented within 18 months of each other with acute midgut volvulus secondary to intestinal malrotation. Clinicians should be aware of this rare but serious cause of abdominal pain.
