This exhibit will stress that the differential diagnosis for hydronephrosis and abdominal masses is different for a female fetus than a male fetus.  Also, anomalies exclusively seen in female fetuses will be stressed, such as urogenital sinus and cloacal malformations, so they are not mistaken for bladder outlet obstruction which is much more common in male fetuses.

Introduction: We will present epidemiologic data that some anomalies are exclusively seen in female fetuses (i.e. cloaca, ovarian cysts, urogenital sinus) or are more common in female fetuses (i.e. duplication anomalies) and therefore should rise to the top of the differential diagnosis when genitourinary anomalies are diagnosed in the female fetus. Case examples will be shown: Complications of renal duplication (ectopic ureterocele, partial cystic dysplasia), hydrocolpos (distended vagina presents as cystic mass), Cloaca/urogenital sinus (imaging of perineum shows one orifice versus two), Ovarian cyst (hemorrhage and torsion complications), clitoromegaly (from congenital adrenal hyperplasia).  Summary: Differentiationg features of above diagnoses will be stressed with tables and flow charts.
