Persistent cloaca is a very rare congenital anomaly with a single common perineal opening for the genital, urinary and gastrointestinal tracts, which arises from defects in the embryonal process of descent of urorectal septum or fusion to cloacal membrane. Anomalies associated with persistent cloaca are found in the upper urinary tract, gastrointestinal tract, cardiovascular system, central nervous system and respiratory system, which are not easily detected through ultrasound during pregnancy. It has been reported that if those anomalies are diagnosed early, they can be corrected surgically. We present a case of persistent cloaca with hydrocolpos confirmed by autopsy after emergency cesarean section which was initially presented as a huge abdominal cystic mass and bilateral hydronephrosis by ultrasound at 34 weeks of gestation.
Key Words: Persistent cloaca, hydrocolpos
