目的分析3例膀胱癌肉瘤的影像学表现特点,提高对其认识。资料与方法搜集经病理确诊的3例膀胱癌肉瘤进行分析,并结合文献进行讨论。结果 3例膀胱癌肉瘤中2例在CT上表现为较大范围不规则的膀胱壁增厚或无蒂肿块,其中1例增强扫描强化较均匀,1例表现为表面或黏膜下强化;1例表现为广基底的突起肿块伴表面不规则钙化,增强扫描强化不均匀。结论膀胱癌肉瘤发病率低,影像上相对缺乏特异性,诊断主要靠病理组织学检查及免疫组织化学染色。但如果病变内部有钙化,MR T2W I像上信号不均且不出现动脉早期显著强化,则应考虑膀胱癌肉瘤的诊断。
Objective To analyze the imaging features of 3 cases of bladder carcinoma and improve their understanding. Materials and Methods Collection of 3 cases of pathologically diagnosed bladder cancer sarcoma were analyzed and discussed with the literature. Results In 3 cases of bladder cancer, 2 cases showed irregularly enlarged bladder wall with thickened or undiagnosed masses on the CT. Among them, 1 case showed enhancement of the contrast enhancement, 1 case showed superficial or submucosal enhancement, 1 case The performance of the wide base of the protruding mass with irregular calcification of the surface, enhanced scan enhancement uneven. Conclusions The incidence of bladder cancer is low, and the relative lack of specificity in imaging. The diagnosis mainly depends on histopathology and immunohistochemical staining. However, if there is calcification inside the lesion, MR T2WI is like the signal uneven and does not appear significant early enhancement of the artery, you should consider the diagnosis of bladder cancer sarcoma.
