Renal Pelvis Urothelial Carcinoma With Bowel Metastases.

Urothelial carcinoma is the fourth most common genitourinary tumor with the majority of the tumor involving the urinary bladder. Only 5% involves the renal pelvis and ureter. Metastatic urothelial carcinoma of the renal pelvis frequently involves the lymph nodes, lung, liver, bone, and peritoneum. We share rare interesting F-FDG PET/CT images of a 60-year-old man with metastatic urothelial carcinoma of the renal pelvis to the bowel.
