目的探讨多层螺旋CT(MSCT)对腹膜后纤维化的诊断价值。方法分析经临床病理证实的11例腹膜后纤维化的临床及多层螺旋CT表现。结果11例患者中男性5例、女性6例,平均年龄52.7岁。特发性8例,继发性3例。多层螺旋CT平扫及经多平面重建,病变表现为腹膜后间隙或盆腔间隙的低密度、不均匀密度或等密度弥漫性浸润病变6例,不规则肿块样病变5例,增强检查显示为病变呈不同程度强化。6例伴有肾盂及输尿管扩张积水。结论多层螺旋CT及其多平面重建能很好显示腹膜后纤维化病变的各种表现,腹膜后间隙出现弥漫浸润性或不规则肿块样病变,并合并肾盂及输尿管扩张积水时应考虑到本病诊断。
Objective To investigate the diagnostic value of multi-slice spiral CT (MSCT) for retroperitoneal fibrosis. Methods Clinical and multi-slice spiral CT findings of 11 cases of retroperitoneal fibrosis confirmed by clinicopathology were analyzed. Results Of the 11 patients, there were 5 males and 6 females, with an average age of 52.7 years. Idiopathic in 8 cases, secondary in 3 cases. Multi-slice spiral CT plain scan and multiplanar reconstruction, the lesions showed retroperitoneal space or pelvic space of low-density, non-uniform density or density of diffuse infiltration of lesions in 6 cases, irregular mass-like lesions in 5 cases, enhanced examination showed Lesions were enhanced to varying degrees. 6 cases with renal pelvis and ureteral dilatation of water. Conclusions Multi-slice spiral CT and its multiplanar reconstruction can well show the various manifestations of retroperitoneal fibrosis, with diffuse infiltration or irregular mass-like lesions in the retroperitoneal space, which should be considered when combined with pelvis and ureteral dilatation Diagnosis of the disease.
