title: Prenatal diagnosis of cloacal malformation.
abstract: Cloacal malformation is a rare abnormality, occurring only in females and characterized by a direct communication between the gastrointestinal, urinary, and genital structures resulting in a single perineal opening. We report 2 cases of prenatal diagnosis of this condition with a varied ultrasonic appearance including fetal ascites, cystic retrovesical mass, ambiguous genitalia, nonvisualization of the bladder, and oligohydramnios.
