目的探讨膀胱非上皮性肿瘤的MDCT表现特征。方法搜集经病理证实的19例膀胱非上皮性肿瘤患者的临床、膀胱镜和MDCT平扫及四期增强检查资料,结合相关文献分析MDCT表现特征。结果 19例膀胱非上皮性肿瘤中,良性肿瘤11例,其中平滑肌瘤6例,嗜铬细胞瘤4例,炎性肌纤维母细胞瘤1例;恶性肿瘤8例,其中原发性淋巴瘤3例,胚胎性横纹肌肉瘤2例,纤维肉瘤、低度恶性间质瘤及神经内分泌癌各1例。MDCT对膀胱非上皮性肿瘤的良恶性诊断准确率为89.47%(17/19),病理类型诊断准确率为63.16%(12/19)。5例膀胱镜提示膀胱腔内肿瘤,诊断为膀胱癌,14例膀胱镜提示膀胱黏膜光滑,诊断为黏膜下病变。结论膀胱非上皮性肿瘤各自有一定的MDCT表现特征,仔细分析大部分可正确诊断,有效地指导临床选择合适的治疗方案。
Objective To investigate the features of MDCT in bladder non-epithelial tumors. Methods The clinical, cystoscopic, MDCT and IV enhanced data of 19 patients with non-epithelial bladder tumor confirmed by pathology were collected, and the features of MDCT were analyzed with related literatures. Results Of the 19 cases of non-epithelial bladder tumor, 11 were benign tumors, including 6 leiomyoma, 4 pheochromocytoma and 1 inflammatory myofibroblastoma. There were 8 malignant tumors, including primary lymphoma 3 Cases, 2 cases of embryonal rhabdomyosarcoma, fibrosarcoma, low grade stromal tumor and neuroendocrine carcinoma in 1 case. The diagnostic accuracy of MDCT in benign and malignant bladder neoplasms was 89.47% (17/19), and the diagnostic accuracy of pathological type was 63.16% (12/19). 5 cases of cystoscopy prompted bladder tumor, the diagnosis of bladder cancer, cystoscopy in 14 cases prompted a smooth bladder mucosa, the diagnosis of submucosal lesions. Conclusions Bladder non-epithelial tumors have their own characteristics of MDCT performance, a careful analysis of most of the correct diagnosis can effectively guide the clinical choice of appropriate treatment.
