【摘要】 目的分析总结腹膜后纤维化患者超声声像图特征表现。方法回顾性分析2000年2月至2012年10月深圳市龙岗中心医院确诊的13例腹膜后纤维化患者超声声像图特征。结果 (1)13例患者中原发性腹膜后纤维化10例,继发性腹膜后纤维化伴有肿瘤者3例。(2)11例患者腹膜后腹主动脉中下段的前壁及两侧壁可见厚度不一的弥漫性条状低回声包绕,形态不规则,范围不等,1例表现为边界较清晰的低回声团块。10例团块内部回声均匀,2例团块内部回声不均匀,可见少量细线状纤维分隔样稍高回声。彩色多普勒血流成像示团块内未见明显的血流信号。其中3例团块同时包绕下腔静脉,3例病变向下延伸至髂血管周围。(3)11例患者(84.6%)伴有不同程度的肾积水,10例同时合并输尿管扩张。肾积水合并输尿管扩张者可见低回声病变包绕输尿管。输尿管局限性狭窄2例。结论超声检查可作为腹膜后纤维化首选的有效诊断手段。更多还原

【Abstract】 Objective To analyze the ultrasonographic features of retroperitoneal fibrosis (RPF).Methods Totally 13 patients with retroperitoneal fibrosis from February 2000 to October 2012 in the Long Gang central Hospital of Shenzhen were retrospectively analyzed.Results In all patients who underwent ultrasound examination,there were ten cases of idiopathic RPF and three cases of secondary RPF with abdominal tumors.In 11 cases,the masses were hypoechoic locating at retroperitoneum and surrounding the abdominal aorta without definitive margin.One case showed hypoechoic mass with clear boundary.In ten cases,the internal echogenicity of masses were uniform.In two cases,the internal echogenicity of masses were uneven with a small amount of fibrous separator with slightly higher echogenicity.No blood was found in all masses.The encasement of inferior vena cava was found in three casesand the masses extended to iliac arteries in three cases.Hydronephrosis could be found in 11 patients (84.6 %) and ureter dilatation was found in ten cases.Ureteral localized stenosis were found in two cases.Conclusion Ultrasonography is a preferred imaging method in diagnosing RPF.更多还原
