A complex of congenital malformations in the anococcygeal region, in various combinations and degrees of seriousness. It consists of the triad of sacral defect (scimitar sacrum - crescentic bony defect and malsegmentation), anorectal malformation (anal stenosis, anal extopia, and imperforate anus), and presacral anomaly (anterior meningocele, teratoma, or cyst). Inheritance is autosomal dominant.
The triad of anorectal malformation, sacral bony abnormality and a presacral mass was first described by T. Bryant in 1838, then by R. L. J. Kennedy in 1926, and K. M. Ashcraft and T. M. Holder in 1974.
