| 摘 要： | 目的提高肾血管平滑肌脂肪瘤（angiomyolipoma，AML）的CT诊断水平。方法回顾性分析31例肾AML患者的临床资料并探讨其CT诊断。结果CT检查发现含脂肪成分者26例，其中常规层厚发现脂肪成分20例，薄层发现（常规不能确定的）脂肪成分6例；CT检查无明显脂肪成分者5例，其中MRI检查T1WI呈等信号、T2WI呈低信号确诊为肾AML2例，误诊为肾癌2例，不能定性1例，该3例术中行冰冻活检确诊为肾AML。结论CT对肾AML诊断的关键是在肿瘤中测得脂肪密度影，对于少脂或无脂的AML，薄层CT扫描可提高诊断准确率；CT结合MRI、B超检查可使确诊率明显提高；术中冰冻活检对明确诊断有决定性意义。 |

| Abstract: | Objective To improve the proficiency in CT diagnosis of the renal angiomyolipoma(AML).Methods Clinical data of 31 cases of renal AML were retrospectively analyzed and discussed.Results CT scan confirmed adipose tissue in 26 cases,of which 20 cases were detected by routine slice scan and 6 cases detected by lamellar scan(undetermined by routine slice scan).CT scan revealed absence of evident adipose tissue in 5 cases,of which 2 cases were diagnosed as AML with MRI examination indicating isointensive signal o... |
