目的:对肾癌CT表现进行研究分析,便于提高诊断肾癌正确性。方法:选取100例通过病例诊断为肾癌患者,分析其CT表现。结果:1例通过活检病理证实,99例通过肾根治性切除术和肾部分切除术和病例证实。肿瘤直径为1.5-16.0cm,平均直径为(8.4±2.5)cm;97例为单发病灶,1例为单侧2个病灶,1例为双侧各1个病灶,1例为双侧各2个病灶。其中,79例为透明细胞癌,7例为乳头状癌,6例未归类癌,5例为嫌色细胞癌,3例为多房性透明细胞癌。42个肿瘤在左肾,58个肿瘤在右肾。结论:不同类型肾癌有其独特CT表现,显著提高诊断鉴别准确性。
OBJECTIVE: To study the CT findings of renal cell carcinoma so as to improve the diagnosis of renal cell carcinoma correctly. Methods: 100 patients with renal cell carcinoma who were diagnosed as cases were selected and their CT findings were analyzed. Results: One case was confirmed by biopsy and 99 cases were confirmed by radical nephrectomy and partial nephrectomy. The tumor diameter was 1.5-16.0 cm with an average diameter of (8.4 ± 2.5) cm. 97 were single lesions, 1 was unilateral 2 lesions, 1 was bilateral and 1 was lesion, 1 was bilateral 2 lesions. Among them, 79 were clear cell carcinoma, 7 were papillary carcinoma, 6 were not classified carcinomas, 5 were chromophobe and 3 were multilocular clear cell carcinoma. 42 tumors in the left kidney, 58 tumors in the right kidney. Conclusion: Different types of renal cancer have their unique CT findings, significantly improving the diagnostic accuracy.
