摘要
目的评价CT诊断腹膜后纤维化的价值。方法分析经临床病理证实的9例腹膜后纤维化的CT表现。9例均接受CT平扫及增强扫描,采用多平面重建(MPR)技术行后处理。结果所有患者CT平扫表现腹膜后近似于肌肉密度的不规则形软组织病变,包绕腹膜后大血管,6例伴有肾盂输尿管扩张积水。增强扫描示8例病变不同程度强化,1例无明显强化。结论CT能很好显示腹膜后纤维化病变的各种表现,当腹膜后病变包绕腹膜后大血管,合并肾盂及输尿管扩张积水时应考虑到本病。
Objective To assess the value of CT in the diagnosis of the retroperitoneal fibrosis （RPF）. Methods Nine patients of RPF proved clinical pathologically underwent CT plain and contrast enhancement scanning, and the images were re constructed with multi-planar reconstruction （MPR） technique. Results CT plain scan showed homogeneous tissue isodensity to muscle and enveloping the great blood vessels in retroperitoneal space in all 9 patients, as well as hydronephrosis and dilatation of the ureters in 6 patients. After contrast enhancement, lesions in 8 patients enhanced differently. Conclusion CT can show the manifestations of RPF. RPF should be considered when a mass in retroperitoneal space, especially with hydronephrosis and dilatation of the ureter is found.
