title: Computed tomographic findings of Bellini duct carcinoma of the kidney.
abstract: OBJECTIVE
  To analyze CT findings of Bellini duct carcinoma, a rare variant of renal cell carcinoma.
  
  
  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.
  
  
  CONCLUSIONS
  Bellini duct carcinoma should be suspected in cases with these CT findings.
