Abstract：Objective To investigate the spiral CT features of renal clear cell carcinoma (ccRCC) and lack of fat angiomyolipomas (RAml),and to explore its diagnostic value for the two kinds of diseases.Methods The data of spiral CT scanning about 2 patients with ccRCC (group A) and 18 patients with Raml (group B) who were dianosed in our hospital from February 2012 to November 2016 were retrospectively analyzed.The CT value and morphological characteristics,basic data were statistical analyzed and compared between two groups,Resuts The patient's age and the lesion size in group A were significantly higher than those in group B (P ＜ 0.05).The single number of people in group A accounted for 100％ (22/22),which was significantly higher than [61.11％ (11/18)] in group B (P ＜ 0.05).The CT values at cortex stage,pelvic stage in group A were (133.5 ± 34.8) Hu,(153.2 ± 37.5) Hu,respectively,which were significantly higher than those in group B (P ＜ 0.05).Moreover the necrosis capsule lesion and the number of pseudocapsule in group A were significantly higher than those in group B,however,the patient numbers with scissors sign,cortex cocking sign,combined bleeding and macula sign in group A were significantly lower than those in group B (P ＜ 0.05).In addition the patients in group A were mostly heterogeneous enhancement,howeverr,the patients in group B were substantially uniform strengthening (P ＜ 0.05).TLC reconstruction showed there were 8 cases of micro fat areas in group B (44.44％),however,no case was observed in group A,there were significant differences between two groups (P ＜ 0.05).Conclusion Spiral CT has important value in diagnosis of ccRCC and lack of fat RAml,therefor,which is worthy of clinical popularization and application.
