Complete caudal duplication syndrome

Caudal duplication syndrome (CDS) is associated with duplications involving the gastrointestinal, genitourinary, and spine/spinal cord. It is rare to encounter a single infant with all of the mentioned abnormalities, meanwhile, with duplex pelvis and both lower limbs. Here we firstly present a male infant with an omphalocele; bilateral cryptorchidism; congenital intestinal malrotation; spina bifida; duplex pelvis, lower limbs, penis, urogenital system, ileum, colon, rectum, anus, and blood vessels of pelvic. We call it complete caudal duplication syndrome. The first-stage of operation was performed and the 4-year follow-up showed no obvious growth and development restriction. It was planned to perform second-stage surgery.
