目的：评价ＣＴ扫描在小肾癌诊断中的应用价值。方法：回顾性分析１１例经手术病理证实为小肾癌（直径＜ ３．０ ｃｍ ）的Ｂ超和ＣＴ资料。结果：１１ 例小肾癌病人中Ｂ超诊断肾囊肿２例、肾良性肿瘤１ 例、肾实性占位８例；ＣＴ诊断畸胎瘤１例、肾脏恶性肿瘤１０例。ＣＴ表现：①ＣＴ平扫为软组织密度结节、无钙化及脂肪组织１０例；②增强扫描显著强化１０例（△ＣＴ值＞ ４０ ＨＵ）；③肿瘤—肾实质界面模糊不清６例、清晰而不锐利４例。结论：ＣＴ检出小肾癌优于Ｂ超，根据小病灶的密度、边缘及强化程度等特征性ＣＴ表现术前能诊断为小肾癌。
Objective: To evaluate the value of CT scan in the diagnosis of small renal cell carcinoma. Methods: A retrospective analysis of 11 cases of small renal cell carcinoma confirmed by pathology (diameter <3.0 cm) B ultrasound and CT data. Results: Of the 11 patients with small renal cell carcinoma, 2 were diagnosed as renal cysts by B ultrasound, 1 was renal benign tumor and 8 was renal solid. 1 CT was diagnosed as teratoma and 10 as renal malignancy. CT findings: CT scan for soft tissue density nodules, no calcification and adipose tissue in 10 cases; ② enhanced scan significantly enhanced in 10 cases (△ CT value> 40 HU); ③ tumor - renal parenchyma interface fuzzy 6 cases, clear and Not sharp 4 cases. Conclusions: Small renal cell carcinoma (CT) is superior to B-mode ultrasonography in diagnosing small renal cell carcinoma according to the characteristic CT findings such as density, margins and degree of enhancement of small lesions.
