摘要
目的：评价轮缘征对输尿管结石在ＣＴ诊断和鉴别诊断中的价值。材料与方法：腹部平片无异常，在静脉尿路造影像上怀疑输尿管阴性结石患者５１例，随后进行ＣＴ平扫来验证输尿管阴性结石的存在与否以及轮缘征的显示率。结果：除２例因结石染色明确诊断外，４９例ＣＴ扫描显示结石者４３例，检出率为８７．７％。其中输尿管结石伴轮缘征者２９例，占６７．４％，结石平均直径为３．７ｍｍ，ＣＴ值１００～４２２ＨＵ。轮缘征最大直径１３．０ｍｍ，平均６．４ｍｍ，ＣＴ值为１４～２２ＨＵ。未出现轮缘征者１４例，结石平均直径为５．８ｍｍ。结论：轮缘征是诊断输尿管结石较可靠的ＣＴ征象，具有较高的诊断价值，此征还可与静脉石和其他性质的钙化具有鉴别意义。
Objective: To discuss the imaging diagnosis of pelvic lipomatosis.Materials and Methods:The imaging findings of 6 cases with pelvic lipomatosis were analyzed retrospectively. CT and ultrasonography (US) were performed in all 6 cases, together with barium enema (BE) in 3 cases and IVU in 2 cases.Results:(1) Displacement of the urinary bladder, lower ureter, rectum and sigmoid due to external compression was seen on BE and IVU; (2) Solid and benign space occupying lesions in pelvic cavity were demonstrated on US; (3) The space occupying lesions showed fat density on CT scan.Conclusion: CT can be served as the first choice in diagnosing pelvic lipomatosis.
