目的分析肾细胞癌的CT表现,探讨CT平扫及增强扫描对该类疾病的诊断价值。方法对手术和病理证实的56例肾细胞癌进行回顾性分析,所有病例均行平扫和增强扫描。结果肾透明细胞癌48例,肾乳头状癌6例,肾嫌色细胞癌1例,肾集合管癌1例。上述各型有其特征性的CT表现,肾透明细胞癌呈不均匀而富血供;乳头状癌不均匀而少血供;嫌色细胞癌呈少血供改变,内可见星茫状强化;集合管癌累及肾皮质和肾髓质,呈少血供改变,边界不清。结论常见RCC亚型有其特征性的CT表现,,有助于鉴别诊断。
Objective To analyze the CT manifestations of renal cell carcinoma and to explore the diagnostic value of CT plain scan and enhanced scan in these diseases. Methods Retrospective analysis was performed on 56 cases of renal cell carcinoma confirmed by surgery and pathology. All patients underwent plain scan and enhanced scan. Results 48 cases of renal clear cell carcinoma, papillary renal cell carcinoma in 6 cases, 1 case of chromophobe renal cell carcinoma, renal tubular cancer in 1 case. The above types have their own characteristic CT manifestations of renal clear cell carcinoma was uneven and rich blood supply; papillary carcinoma uneven and less blood supply; chromogenic cell carcinoma showed a small blood supply changes, showing the strengthening of the star-like; Tubal cancer involving the renal cortex and renal medulla, showed less blood supply changes, the border is unclear. Conclusions Common RCC subtypes have their characteristic CT findings, which can be helpful in differential diagnosis.
