TYPE-1 RECTAL DUPLICATION - ASSOCIATED CONGENITAL-MALFORMATIONS AND ULTRASOUND DIAGNOSIS

Type I duplication of the rectum is a rare condition that in most repo rted cases does not occur in association with other congential malform ations. We describe three cases, two of which had duplications of othe r structures: the first had a functioning supernumerary pelvic kidney, the second a duplication of the bladder, urethra, and vagina; the thi rd had no associated malformations but was unusual, because the duplic ation cyst lay anterior to the rectum, and unique in that the diagnosi s of an intra-abdominal cyst was made by ultrasonic examination.
