Centrally Infiltrating Renal Masses on CT: Differentiating Intrarenal Transitional Cell Carcinoma From Centrally Located Renal Cell Carcinoma

Abstract

Intrarenal TCC can be recognized with a high accuracy on CT; global impression showed the best diagnostic performance. A solid, homogeneously enhancing mass that is centered on the collecting system and extends toward the ureteropelvic junction combined with a focal pelvicalyceal filling defect and preserved renal outline is more likely to be an intrarenal TCC than a centrally located RCC.
