| 【摘要】收集经手术病理证实的原发性膀胱黏液腺癌伴印戒细胞癌一例。患者行盆腔 MRI 及CT检查，MRI示膀胱三角区不规则宽基底占位，病变的顶部形状呈菜花状及棉絮状，病变T2WI呈高信号，DWI轻度扩散受限；膀胱固有肌层破坏中断，病变侵犯双侧精囊腺、输精管、双侧输尿管膀胱入口受侵犯伴以上扩张积水，前列腺上部受侵犯。CT增强扫描示持续性轻度不均匀性强化。本病十分少见，临床表现缺乏特异性，因其富含黏液成分，MRI特别是T2WI对黏液成分的显示具有一定特征性，最终确诊需要依靠病理。 |

| Abstract
A case of primary bladder mucinous adenocarcinoma with signet ring cell carcinoma was collected.Pelvic MRI and CT examination were performed. MRI showed irregular and wide basalspace-occupying lesions in thetrigone of bladder.The apicalshapeof the lesion was cauliflower-like and cotton-wool, with a high signal on T2WI and mild limited diffusion on DWI.The muscularis propria of bladderwas damaged, and bilateral seminal vesicles, vas deferens, ureteral and bladder inlet were invaded with hydronephrosis and ureterectasis.The upper part of the prostate was also invaded. Enhanced CT scan showed persistent mild inhomogeneity enhancement.This disease is very rare and lacks specificity in clinical manifestations.Because it is rich in mucus components, MRI, especially T2WI, has certain characteristics for the display of mucus components. The final diagnosis depends on pathology |
