Abstract

Objective To investigate the CT findings of solid tumors of renal non-clear cell carcinoma so as to improve the level of diagnosis and differential diagnosis of these tumors. Methods The CT findings of 35 patients renal solid tumors of non-clear cell carcinoma with surgically and pathologically proved were analyzed retrospectively. Results The CT fingings of papillary renal cell carcinoma (n=4), chromophobe cell renal carcinoma(n=13), renal angiomyolipoma (n=12) and oncocytoma(n=6) are as follows: tumor necrosis in 3 cases, 4 cases, 3 cases and 0 case, respectively, hemorrhage in 1 case, 3 cases, 2 cases and 0 case, respectively, calcification in 0 case, 3 cases, 1 case and 0 case, respectively; tumor capsule in 2 cases, 6 cases, 0 case and 2 cases, respectively; cup sign in 3 cases, 6 cases, 8 cases and 1 case, respectively, central scar in 0 case, 2 cases, 1 case and 2 cases, respectively, intra-tumoral blood vessels in 1 case, 9 cases, 9 cases and 2 cases, respectively, peripheral vascular dilatation in 1 case, 4 cases, 3 cases and 2 cases, respectively; mild and moderate enhancement in 3 cases, 4 cases, 2 cases and 1 case, respectively; marked enhancement in 1 case, 9 cases, 10 cases and 5 cases, respectively, spoke-wheel-like enhancement in 1 case, 1 case, 0 case and 0 case, respectively, segmental enhancement inversion in 1 case, 1 case, 1 case and 0 case, respectively. Conclusion The CT findings of renal solid tumors of non-clear cell carcinoma has some characteristics and is helpful in the diagnosis and differential diagnosis.
