This fetus was scanned for the first time at 35 weeks of gestation. There was anhydranmnios. We thought at that time that both kidneys were absent, but they appeared to be very dysplastic. The two identical ovoid shaped structures represented a didelphic uterus, filled with mucus (1 MB video-clip). The connection between these uterine horns and a cystic perineal mass (hydrometrocolpos) became visible after intrauterine instillation of saline.
