title: The spectrum of peripelvic cysts.
abstract: Nineteen peripelvic cysts with unusual findings are discussed. While usually an incidental radiographic finding, these cysts may obstruct the collecting system and yet not be apparent on nephrotomography. They may also be confused with renal sinus lipomatosis and, ultrasonographically, they may mimic hydronephrosis.
