Closed bladder exstrophy (pseudoexstrophy) associated with mesodermal anomalies.

Ultrasonographic findings have been well described in exstrophyl-4; however, to our knowledge no men· tion of dosed bladder exstrophy (pseudoexstrophy) occurs in the ultrasonography literature. Exstrophy is a rare congenital anomaly seen in 1 in 40,000 live births,5 and exstrophy variants including dosed exstrophy are extremely rare. We present a case report with pathologic correlation and discuss the embryology of exstrophy and closed exstrophy.
