目的:结合病理分型对肾细胞癌的CT影像特点进行分析,探讨其诊断准确率。方法:将三台县中医院2012年10月-2014年10月接收的肾细胞癌36例患者作为研究对象,回顾性分析其临床资料,术前均给予其CT检查(平扫与动态增强扫描相结合),总结其CT影响特点,并与病理结果进行对照。结果:本组36例患者中透明细胞癌为25例(69.4%),乳头状癌为4例(11.1%),嫌色细胞癌为3例(8.3%),多房囊性肾细胞癌为2例(5.6%),集合管癌与颗粒细胞癌均为1例(2.8%);病理分型将多房囊性肾细胞癌与颗粒细胞癌归为透明细胞癌,且其血供较为丰富,扫描后更为强化;嫌色细胞癌与乳头状癌血供少,强化程度明显低于透明细胞癌。结论:各型肾细胞癌CT影像表现的特异性较差,在很大程度上需依赖病理,将病理与CT影像特点进行结合后有助于诊断与鉴别诊断。
OBJECTIVE: To analyze the characteristics of CT images of renal cell carcinoma in combination with pathological classification and discuss the diagnostic accuracy. Methods: Thirty-six patients with renal cell carcinoma received from Santai Hospital of Traditional Chinese Medicine from October 2012 to October 2014 were studied retrospectively. The CT data were obtained before operation (plain and dynamic contrast-enhanced scan Combined), summarizes the characteristics of CT impact, and pathological results were compared. Results: Among the 36 patients, 25 (69.4%) had clear cell carcinoma, 4 (11.1%) had papillary carcinoma, and 3 (8.3%) had chromophobe carcinoma. The incidence of multicellular cystic renal cell carcinoma was 2 cases (5.6%), tuberculous and granular cell carcinoma were 1 case (2.8%); pathological type of polycythetenic renal cell carcinoma and granulosa cell carcinoma classified as clear cell carcinoma, and its blood supply is more abundant , More enhanced after scanning; chromophobe and papillary carcinoma less blood supply, the degree of enhancement was significantly lower than clear cell carcinoma. Conclusion: The CT images of all kinds of renal cell carcinoma show poor specificity. To a large extent, CT images are dependent on the pathology. Combined with the features of pathology and CT images, it is helpful to diagnose and differentiate CT images.
