Abstract

The "drooping lily" sign is identified on intravenous urography or voiding cystourethrography in patients with a duplicated renal collecting system and refers to inferolateral displacement of a functioning lower pole moiety by an obstructed upper pole collecting system. In this case, a 2-month-old girl with a prenatal diagnosis of hydronephrosis was found to have a "scintigraphic drooping lily" sign on ^99mTc-dimercaptosuccinic acid renal scan. Evaluation with ultrasound and voiding cystourethrography confirmed a duplicated collecting system and obstructed upper pole moiety. Correlation with anatomic imaging can help avoid mistaking the scintigraphic "drooped" lower pole for an inferiorly positioned normal kidney.
