摘　　要：目的 分析肾嫌色细胞癌（CRCC）的CT特征与病理表现，提高对CRCC的诊断能力。方法 回顾性分析本院经手术病理证实的40例CRCC患者，对照分析其CT特征与病理。结果 40例CRCC均为单发病灶，类圆形或椭圆形，平均直径6.8 cm。30例病灶平扫CT值均比肾实质高；9例等密度，1例稍低密度。病灶密度均匀，18例见星芒状或弧形稍低密度影/瘢痕，21例病灶突向肾盂肾盏方向生长。30例病灶位于肾髓质，10例位于皮髓质。40例共3种强化方式，6例 “快进快出”强化，8例“渐进性”强化，26例“慢进慢出”强化。23例有包膜，边界清楚。结论 CRCC的CT特征性表现为边界清楚，形态规整，平扫稍高密度，均质，膨胀性生长，乏血供肿瘤，并能反映病理特征，在术前诊断中具有重要价值。Objective To analyze CT features and pathological characteristics of chromophobe renal cell carcinoma（CRCC）and improve the diagnostic accuracy of this tumor. Methods CT findings of 40 cases with CRCC proved surgically and pathologically were reviewed retrospectively and compared their CT manifestations with pathological results.Results 40 cases of CRCC were single,circular or elliptical,with an average diameter of 6.8 cm.CT values of 30 tumors were higher than that of the renal parenchyma.CT values of 9 cases were equal to the renal parenchymapand 1 case was lower than that of the renal parenchyma.On CT images,all tumors tended to appear as homogeneity.Among them, 18 cases had astral form or arc low density/scar, 21 cases grew in the direction of the renal pelvis.30 cases were located in the renal medulla,and 10 cases in the renal cutaneous medulla.Moreover,there were 3 patterns of enhancement,in which 6 cases were ＂fast-in fast-out＂, 8 ＂progressive enhancement＂ and 26 ＂slow-in, slow-out＂. 23 cases had enveloped membrane and the boundary was clear. Conclusion The CT features of CRCC are characterized by clear boundaries, regular shape,light high density on CT plain scan, homogeneity, expansive growth and poor blood supply.The above-mentioned CT manifestations further reflect their pathological features, which are of ~reat value in accurate diagnosis of CRCC preoperatively.
