KEY FACTS

  • Terminology

    • Imaging

      • Top Differential Diagnoses

        • Clinical Issues

          TERMINOLOGY

          • Synonyms

            • Cloacal malformation
          • Definitions

            • Anorectal malformation in female patients in which rectum, urethra, & vagina converge to form common channel that drains to single perineal orifice (which allows clinical diagnosis)
              • Imaging may be performed in neonate (to fully assess anomalies), after colostomy prior to definitive repair (to discern fine details of connections), & postrepair for complications
