Two cases of bizarre rib anomalies associated with intestinal malformation.

Two cases of bizarre skeletal anomalies associated with intestinal malformation are presented. One patient had ileal atresia and Hirschsprung's disease, and the other anorectal malformation. Abnormalities in the number and morphology of ribs and vertebrae were present. Esophageal atresia often is associated with skeletal abnormalities, including supernumerary ribs, but these usually are not severe. Despite their severe costal malformations, neither patient had any complication after surgery to correct their intestinal malformation.
