Two patients with renal cell carcinoma and one patient with metastasis to the kidney from colorectal cancer are reported because all three cases manifested at computed tomography (CT) as a renal mass invading the pelvicaliceal system and radiologically simulating transitional cell carcinoma. Recognition that the CT finding of a renal mass with invasion of the pelvicaliceal system is not always indicative of a transitional cell carcinoma broadens the differential diagnosis in this setting and might potentially alter the diagnostic and therapeutic approach.
