【摘要】：目的本次主要对多层CT用于乏脂性肾血管平滑肌脂肪瘤、非透明细胞肾癌患者鉴别诊断中的临床效果进行探讨,旨在为临床有效诊断提供参考依据。方法选取我院2014年3月至2016年3月收治并已确诊的乏脂性肾血管平滑肌脂肪瘤、非透明细胞肾癌患者患者共54例,对所有患者的临床资料进行回顾性分析,其中10例乏脂性肾血管平滑肌脂肪瘤患者,21例乳头状肾细胞癌患者,23例嫌色细胞癌患者,所有患者均于术前给予多层CT平扫和增强扫描。结果乏脂性肾血管平滑肌脂肪瘤与乳头状肾细胞癌、嫌色细胞癌比较,女性的患病几率更高,P0.05,具有可比性;且乏脂性肾血管平滑肌脂肪瘤较后两者要小,P0.05。当乏脂性肾血管平滑肌脂肪瘤平扫CT值的临界值在41.2Hu时,其特异性为77.5%,敏感性为78.9%;而非透明细胞肾癌平扫CT值的临界值在23.5Hu时,其特异性为79.5%,敏感性为81.3%;当乏脂性肾血管平滑肌脂肪瘤廓清率在-7.3%时,其上述指标分别为84.3%与63.2%;非透明细胞肾癌廓清率在-8.6%时则为84.6%与70.5%;当乏脂性肾血管平滑肌脂肪瘤皮髓期H值在39.4Hu时,其上述指标为68.5%与78.9%,而非透明细胞肾癌皮髓期H值在27.1Hu时上述指标为70.4%、79.9%。结论乏脂性肾血管平滑肌脂肪瘤和非透明细胞肾癌在多层CT中的表现均具有一定的特征,但临床诊断中并不容易被鉴别。
[Abstract]:Objective to investigate the clinical effect of multi-slice CT in differential diagnosis of renal angiomyolipoma and opaque renal cell carcinoma. Methods from March 2014 to March 2016, the diagnosis of adipose renal angiomyolipoma was confirmed in our hospital. The clinical data of 54 patients with opaque renal cell carcinoma were analyzed retrospectively. Among them, 10 patients with renal angiomyolipoma were diagnosed as papillary renal cell carcinoma (papillary renal cell carcinoma). All 23 cases of chromophobe cell carcinoma were examined with multislice CT and contrast-enhanced CT before operation. Results the results were compared with those of papillary renal cell carcinoma and chromophobe cell carcinoma in adipose renal angiomyolipoma. The incidence of disease in women was higher than that of P0.05, which was comparable. Compared with the latter two, adipose renal angiomyolipoma was significantly smaller (P 0.05). When the threshold value of plain scan CT was 41.2 Hu, its specificity was 77.5%. The sensitivity was 78.9; When the threshold of CT scan value of non-transparent cell renal cell carcinoma was 23.5 Hu, its specificity was 79.5% and the sensitivity was 81.3 Hu. When the clearance rate of adipose renal angiomyolipoma was -7.3, the above indexes were 84.3% and 63.2 respectively. The clearance rate of opaque cell renal cell carcinoma was 84.6% and 70.5 at -8.6; The above indexes were 68.5% and 78.9% when the value of H in the medullary phase of renal angiomyolipoma was 39.4 Hu. The above indexes were 70.4% when H value of nontransparent cell renal cell carcinoma was 27.1 Hu. Conclusion the findings of adipose renal angiomyolipoma and opaque cell renal cell carcinoma have some characteristics in multislice CT, but they are not easy to differentiate in clinical diagnosis.
