Splenic Cyst Presenting as Severe Hydronephrosis in a Pediatric Patient

Abstract

Large cystic abdominal masses can represent a diagnostic dilemma despite advanced diagnostic and imaging techniques. We report a case of a large cystic mass initially managed as a giant ureteropelvic junction obstruction, but ultimately found to be a congenital splenic cyst. Focus is placed on the diagnostic evaluation of large cystic abdominal masses.
