OBJECTIVE: To analyze CT findings of Bellini duct carcinoma, a rare variant of renal cell carcinoma. MATERIALS AND METHODS: The CT findings of five cases of Bellini duct carcinoma were reviewed and the findings were recorded. RESULTS: In all cases the affected kidneys maintained the normal outer contours. In four cases the renal masses protruded into the central sinuses. Contrast enhancement was minimal in four cases. CONCLUSION: Bellini duct carcinoma should be suspected in cases with these CT findings.
