Die Ureteral FDG sntal Case of ng System

摘要

Ureteral duplication anomaly is usually diagnosed by ultrasound, voiding cystourethrography, radioisotope renography and sometimes excretory urogram, but there have been not many cases of F-18 FDG PET-demonstrated ureteral duplex. We describe a 68-year-old female without history of abdominal-pelvic malignancy. Under health examination, F-18 FDG PET showed extraordinarily ureteral FDG activity connecting to the upper pole of kidney. Co-registered CT scan displayed duplex renal collecting system by presenting Y-shaped ureter.
