Newborn with one perineal opening for the vagina and urethra and rectum

Fluoroscopic exam of cloacal malformation
AP (above left) and lateral (above right) images during injection of water soluble contrast into the vagina shows a dilated vagina and a duplicated uterus. Lateral image during antegrade injection of water soluble contrast into the patient’s distal mucous fistula (below left) shows a connection between the posteriorly located distal rectum and the posterior aspect of the vagina. Lateral image obtained during filling of the anteriorly located bladder with water soluble contrast through a suprapubic catheter (below right) shows the proximal urethra just inferior to the bladder to be dilated.

The diagnosis was cloacal malformation.
