腹膜后纤维化的多层螺旋CT诊断

MSCT diagnosis of retroperitoneal fibrosis.

目的探讨腹膜后纤维化(RPF)的多层螺旋CT(MSCT)的表现和诊断价值。方法对19例经临床病理证实的腹膜后纤维化的MSCT影像表现及临床资料作回顾性分析。结果腹膜后纤维化的MSCT表现为腹膜后弥漫型肿块及腹膜后脏器的浸润及与周围组织的包裹。19例中13例为肿块型,6例为弥漫型。CT平扫为腹膜后密度较均匀或不均匀的软组织肿块。增强扫描病灶呈不同程度强化。本组11例行MPR多平面重建,可进一步明确病变与周围组织的关系。结论 MSCT检查可明确病变的范围、部位、形态、密度及强化特征,对腹膜后纤维化的诊断有重要临床价值。

Objective To discuss MSCT findings of retroperitoneal fibrosis and their value diagnosis of this disease.Methods MSCT findings and clinical data of 19 cases confirmed with retroperitoneal fibrosis by clinicopathology were retrospectirely analysed.Results MSCT manifestations of retroperitoneal fibrosis included diffuse mass at retroperitoneum.The neighboring organs were enveloped by masses and dilatation of the ureters.13 cases were mass type and 6 cases were diffuse type.Non-contrast MSCT scaning revealed soft tissue mass at retroperitoneum with inhomogenous or homogenous density.After contrast medium injection the lesions were enhanced with different extent.Conclusion MSCT scans have great clinic value in providing information regarding range,location,shape,density and enhanced characteristic.MSCT have vital clinical significance in diagnosis the retroperitoneal fibrosis.
