Abstract
Rectal atresia is a rare anorectal malformation, and its association with other anomalies
is even more rare. This study presents a unique case of co-twin in which the surviving
newborn male underwent surgery due to rectal atresia. Newborn screening tests identified
congenital hypothyroidism. The surgical treatment consisted of three stages and thyroid
hormones were replaced.
