目的：总结腹膜后纤维化（RPF）的多层螺旋 CT（MSCT）影像学征象，提高对此罕见病的认识和诊断水平。方法对11例 RPF 病例的 MSCT 图像资料进行回顾性分析，其中男7例，女4例，平均年龄49．6岁。11例患者均行平扫及增强扫描，并结合多平面重建（MPR）、曲面重建（CPR）和 CT 尿路造影（CTU）后处理图像进行分析。结果11例患者 CT 平扫均表现为腹膜后不规则肿块或弥漫型软组织病变，其中肿块型4例，弥漫型7例，呈等密度或稍低密度；增强扫描有8例轻-中度强化，3例无明显强化；11例患者均不同程度包绕腹膜后大血管、一侧或双侧输尿管。结论MSCT 检查结合 MPR、CPR 和 CTU 后处理技术，可以清晰显示 RPF 的影像学征象及病变范围，对于提高 RPF 早期诊断正确率、指导临床治疗及预后有重要价值。

Objective To summarize the MSCT features of retroperitoneal fibrosis(RPF),and to improve the understanding and diagnosis of this unusual disease.Methods The MSCT data of 11 cases of RPF(7 males and 4 females,mean age 49.6 years)were retrospectively analyzed.All patients underwent CT plan and contrast-enhanced scan.Post-processing technologies included multi-planar reconstruction(MPR),curve planar reconstruction(CPR)and CT urography(CTU). Results CT scan showed irregular retroperitoneal lumps(4 cases)or dispersive soft tissue lesions (7 cases)of isodensity or hypodensity.Contrast-enhanced scan showed mild-to-moderate enhance-ment in 8 cases and no obvious enhancement in 3 cases.The large blood vessels and unilateral or bilateral ureters were enveloped in all the 11 patients.Conclusion MSCT combined with MPR, CPR and CTU can clearly display imaging signs and lesion extent of RPF.Therefore,MSCT has important value for improving early diagnosis accuracy and guiding clinical treatment and progno-sis in patients with RPF.
