Presentation
Infant born with double anal orifices.
Patient Data
Duplication of the lumbar and sacral vertebral bodies with vertebral segmentation anomalies.
Case Discussion
Caudal duplication syndrome (CDS) is a rare congenital anomaly with a prevalence of less than 1 per 100.000 at birth.
Caudal duplication of the distal organs is derived from the hindgut, neural tube, and adjacent mesoderm.
Gastrointestinal duplication includes colon and rectum duplications, which might be associated with duplicated anus openings, imperforate anus, rectal fistula, ventral hernia, omphalocele, and duplication of the terminal ileum, double appendices, Meckel’s diverticulum, intestinal malrotation, and situs inversus.
Urogenital duplications comprise duplication of the external genitalia (double phalluses or vagina), ureters and bladder and uterus.
Common associations include vertebral duplication, spinal dysraphism, kyphoscoliosis of the spine and vertebral body defects, and symphysis pubis diastasis.
