目的分析小肾透明细胞癌的CT表现及其与病理组织的关系。方法选择小肾透明细胞癌患者42例,其中男性27例,女性15例;年龄34~68岁,平均年龄50.6岁。对42例经手术后病理组织证实的小肾透明细胞癌病例进行CT征象及病理组织结果对照分析。结果 CT平扫32例为低密度,8例为等密度,2例为高密度;增强CT扫描皮质期,肿瘤实性部分明显强化,强化峰值≥100 Hu,排泄期迅速下降,低于正常肾实质,呈快进快出特点;不均匀强化26例,均匀强化16例。病理组织36例可见出血、坏死,细胞呈实性排列,6例呈囊性排列;出现小泡样结构2例,出现不规则钙化2例,出现假包膜38例。结论小肾透明细胞癌的CT表现与病理组织类型及肿瘤结构有关,动态增强扫描对小肾透明细胞癌的诊断及制定手术方案有重要意义。
Objective To analyze the CT manifestations of renal clear cell carcinoma and its relationship with pathological tissues. Methods 42 cases of clear cell renal cell carcinoma were selected, including 27 males and 15 females, aged from 34 to 68 years, with an average age of 50.6 years. Forty-two cases of clear cell renal cell carcinoma confirmed by pathology were analyzed with CT and histopathological results. Results CT scan was performed in 32 cases with low density, 8 cases with isodense density and 2 cases with high density. CT scan enhanced the cortical phase, and the solidity of the tumor was obviously enhanced. The peak value of enhancement was ≥100 Hu, the excretion period decreased rapidly and was lower than that of the normal kidney Essence, was fast forward fast features; uneven enhancement in 26 cases, uniform enhancement in 16 cases. 36 cases of pathological tissue showed hemorrhage and necrosis, the cells were arranged in a solid, 6 cases were cystic arrangement; there were 2 cases of vesicle-like structure, irregular calcification in 2 cases, there were 38 cases of pseudocapsule. Conclusions The CT manifestations of small cell renal clear cell carcinoma are related to the type of histopathology and tumor structure. The dynamic contrast-enhanced scan is of great significance for the diagnosis of small clear cell renal cell carcinoma and the development of surgical plans.
