摘要
目的：探讨肾嫌色细胞癌（RCCC）CT表现，提高术前CT诊断准确率。方法：结合手术病理标本特征，回顾性分析4例肾嫌色细胞癌的CT表现及临床资料。结果：肿瘤在CT上均表现为边界清楚的类圆形实性肿块，大小3.5～9.0cm，平均5.43cm。肿块中心均位于肾髓质内，不同程度地向肾窦及肾皮质膨胀样生长。4例病人中，3例肿块平扫呈均匀密度，1例肿块内有散在的小钙化；增强后扫描3例肿瘤呈轻至中度持续强化，密度低于肾实质，1例肿块内有稍低密度影。结论：CT是RCCC的重要检查方法之一，CT表现具有一定特征性，对定性诊断具有重要参考价值，是发现病变、判断预后的可靠方法。
Abstract
Objective: To evaluate the CT appearances of renal chromophobe cell carcinoma(RCCC) and technique of CT. Methods: The CT features, clinical and pathological data of 4 cases of RCCC were analyzed retrospectively. Results: The RCCC showed solitary mass on CT scan, the size ranged from 3.5～9.0cm, with mean size of 5.43cm. The center of masses located in the renal medullary and expanded to cortex. Among the four cases of pre-enhanced CT images in three cases the mass density were homogeneous, one case had scattered spot calcification. On enhanced images, the mass of three cases showed enhancement from slight to moderate and the density lower than the renal parenchyma, and one case with patchy low density in the mass. Conclusions: CT scan plays an important role in RCCC examination and has some peculiar manifestation. It is a good and reliable method for pre-operation diagnosis of RCCC.
