摘要
目的:评价影像诊断腹膜后纤维化(RPF)的应用价值。方法:分析经临床病理证实的9例RPF的IVP、CT、MRI表现。5例行IVP检查;9例均行CT平扫及增强检查,采用CT三维重建成像技术处理;2例行MRI平扫及增强扫描。结果:影像学表现腹膜后不规则形软组织病变,包绕腹膜后大血管,多伴有肾盂输尿管扩张积水。结论:IVP、CT、MRI检查是发现和诊断本病的重要手段,CT和MRI能很好显示RPF病变的各种表现,有利于分期及疗效监测。综合分析各种影像学检查有助于RPF的诊断。
Objective：To evaluate the value of imaging modalities in the diagnosis of the retroperitoneal fibrosis.Methods：Imaging fingdings on intravenous urography（IVU）,computed tomography（CT）,and magnetic resonance imaging（MRI） of retroperitoneal fibrosis in 9 cases confirmed by clinical-pathological diagnosis were analyzed retrospectively.CT including plain and contrast-enhanced scans as well as 3D reformations was performed in all cases.IVU was performed for 5 cases and MRI for 2 cases.Results：The irregular masses encased the great vessels in the retroperitoneal space.Most cases were associtated with hydronephrosis and dilatation of the ureters.Conclusion：Work-up with imaging modalities of IVU,CT,and MRI plays an important role in the detection and characterization of retroperitoneal fibrosis.CT and MR can also help stage the disease and monitor the therapeutic effects.Comprehensive analysis of various imaging examinations is helpful to diagnose the retroperitoneal fibrosis.
