摘要： 目的:探讨特发性腹膜后纤维化(IRF)临床及CT表现。方法: 经病理证实的腹膜后纤维化病例7例，详细分析其临床及CT表现。其中男5例、女2例，平均年龄53.5岁。7例均行CT平扫及增强检查。结果:7例患者起病均较隐匿，无特异性临床表现。均以腰背酸痛及腹部持续性胀痛或隐痛为首发症状，下肢浮肿4例，腹部包块3例，尿路梗阻3例。CT表现病变均呈肿块样生长，平扫呈稍低密度、混杂密度或等密度，增强检查呈不同程度强化。结论:IRF起病隐匿，临床表现无特异性，CT表现多变，如腹膜后出现肿块样病变合并肾及输尿管积水时应考虑到本病诊断。

Abstract: Objective: To investigate the clinical and CT features of idiopathic retroperitoneal fibrosis (IPF). Methods: 7 cases of retroperitoneal fibrosis proved by clinicopathology were presented. The clinical and CT performance of the cases were analyzed. There were 5 males and 2 females, with an average age of 53.5 years. All the cases were idiopathic fibrosis. Plain CT scan and contrast enhancement CT scan were undergone in all cases. Results: The clinical performances of the cases were nonspecific. The first symptoms included abdominal and lumbar pain. Others symptoms included lower extremity swelling (4 cases), abnormal soft-tissue mass (3 cases) and urinary tract obstruction (3 cases).On CT study, well circumscribed masses were showed in 7 cases. The lesions could be hypodensity, inhomodensity or isodensity, and various enhancements by contrast administration. Conclusion: Retroperineal fibrosis is a rare disease with various manifestations on CT study. It should be diagnosed if the mass lesion occurs in retroperitoneal space complicating with hydronephrosis or ureterolysis.
