摘要
目的观察膀胱良性尿路上皮肿瘤(BUT)的CT特点。方法回顾经手术病理确诊的38例(44个肿瘤)BUT的临床和影像学资料,以术后病理作为诊断金标准,分析BUT的CT特征的诊断价值。结果病理证实尿路上皮乳头状瘤(UP)20个、内翻性尿路上皮乳头状瘤(IUP)24个。CT特征:UP直径(11.39±5.93)mm,多呈菜花状(14/20,70.00%),基底部多带蒂(11/20,55.00%),平扫肿瘤与膀胱肌层密度相比多呈等密度(18/20,90.00%),增强扫描均呈中-高度强化;IUP直径(16.21±7.47)mm,多呈菜花状(9/24,37.50%)及乳头状(9/24,37.50%),基底部多带蒂(17/24,70.83%),与膀胱肌层相比,平扫肿瘤密度多呈等密度(20/24,83.33%),增强后呈中-高度强化。结论 BUT的CT表现具有一定特征性;最终确诊需依赖术后病理。
Objective To explore CT features of benign bladder urothelial tumors （BUT）. Methods Clinical and imaging data of 38 BUT patients （44 lesions） confirmed by pathology were retrospectively analyzed. Taking pathology results as gold standards, the diagnostic value of CT features of BUT were assessed. Results There were 20 urothelial papillomas （UP） and 24 inverted urothelial papillomas （IUP）. The diameter was （11.39±5.93）mm in UP and （16.21±7.47）mm in IUP. Most lesions were cauliflower-like in UP （14/20, 70.0%） and cauliflower-like as well as papillary in IUP （each accounted for 37.50% ）, 55.00% （11/20） UP and 70.83% （17/24） IUP had pedicled basement. Eighteen （18/20, 90.00%） UP and 20 （20/24, 83.33%） IUP were isodense in plain CT, while all the lesions enhanced mid-highly after the administration of contrast media. Conclusion The imaging manifestations of bladder BUT have certain characteristic, while the final diagnosis should rely on pathology.
