摘要
目的:探讨泌尿系统炎性肌纤维母细胞瘤(IMT)的CT影像学表现特征,提高诊断水平。材料与方法:经手术病理证实的IMT 8例。女6例,男2例。平均年龄35(13～62)岁。临床主要表现为血尿、尿痛等。病变位于膀胱5例,输尿管2例,尿道1例。行CT平扫8例,行多期增强扫描5例,观察影像学表现特征。结果:CT平扫膀胱病变呈菜花样或类圆形软组织肿物5例,密度均匀或不均匀或伴有坏死,CT值11.5～36.0 Hu,可伴有邻近膀胱壁增厚及周围脂肪间隙模糊;2例输尿管病变均呈边缘光滑的实性肿物,密度均匀并与肌肉等密度,CT值约40.3 Hu;1例尿道病变呈境界较清的肿物伴有钙化,密度稍低不均匀,CT值17.5～22.6 Hu。增强扫描肿瘤动脉期呈均匀或不均匀轻到中度强化,延迟期持续性明显强化,CT值102.7～118.6 Hu。结论:CT影像学特征特别是延迟期强化明显而持久能为泌尿系统IMT的诊断及其鉴别提供重要的信息。
Purpose： Objective To evaluate the CT images performance characteristics of the urinary system inflamma- tory myofibroblastic tumor （IMT） to improve diagnosis. Materials and Methods： The IMT of 8 cases proved by pathologi- cally. 6 people were females, 2 people were males. The average age were 35 （13 - 62 ） years. Main clinical manifestations were hematuria, dysuria and so on. 5 cases were in bladder, 2 cases were in ureter, 1 case was in urinary tract. 8 cases operated CT scan, 5 cases operated enhanced scan, and observed imaging features. Results： CT scan showed a cauliflower bladder disease or round soft tissue masses in 5 cases, even or uneven density or accompanied by necrosis, CT digital were 11.5 -36. 0 Hu, may be associated with bladder wall thickening adjacent to and surrounding fat space fuzzy; ureteral lesions of 2 cases showed a solid mass smooth edges, uniform density and the density and muscle, CT digital were about 40. 3 Hu ; urinary tract lesions of 1 case was more clear in the realm of mass with calcification, lower uniform density, CT digital were 17.5 - 22. 6 Hu. The tumor in arterial phase enhanced scan showed homogeneous or heterogeneous mild to moderate enhance- ment, delayed enhancement was significantly enhanced sustainability, CT digital were 102. 7 -118.6 Hu. Conclusion： CT imaging features of marked enhancement in particular and lasting delayed, provide important information for diagnosis and dif- ferential diagnosis of the urinary system IMT.
