| 目的 探讨肾透明细胞癌的CT、MRI表现。方法 回顾性分析165例经手术病理证实的肾透明细胞癌的CT、MRI表现。结果 165例共有172处病灶。肿瘤的最大径为1~12 cm,平均4.6 cm。本组97.1%(167/172)肾透明细胞癌有共同的CT、MRI表现:平扫呈均匀或不均匀的等、稍低、稍高或混杂密度或信号;增强扫描皮髓期,肿瘤呈不均匀明显强化,强化最明显处强化程度与邻近肾皮质相似或更强。结论 肾透明细胞癌多为富血供性,有特征性CT、MRI表现,可与其他亚型肾细胞癌鉴别诊断。 |

| Objective To investigate the CT and MRI manifestation of renal clear cell carcinoma (RCCC). Methods 165 cases with RCCC proved by surgery and pathology were examined by CT and MRI. Their CT and MRI manifestation were reviewed. Results There were 172 masses in this group. The masses were 1 cm to 12 cm (mean 4.6 cm) in diameter. In this group, 97.1% (167/172) masses of RCCC had the common CT and MRI manifestation: homogenous or inhomogeous, equal, slightly lower, slightly higher or mixed density/signal on non-enhanced images, inhomogenous obvious enhancement after administration of contrast media, and the most obviously enhanced portion of RCCC was isodense/isointense or slightly hyperdense/hyperintense relative to adjacent renal cortex in corticomedullary phase. Conclusion With rich blood supply and characteristic CT/MRI manifestation, most RCCC can be differentiated from the other subtype of renal cell carcinoma. |
