腺性膀胱炎的临床与MRI分析

Clinical and MRI Analysis of Cystitis Glandularis

目的:探讨腺性膀胱炎的临床和MRI诊断特点。方法:对5例经膀胱镜及病理确诊为腺性膀胱炎患者的临床、膀胱镜和MRI表现进行回顾性分析,并复习相关文献。结果:5例患者的主要临床表现为血尿、尿路刺激症状及排尿困难等。病变好发于膀胱颈部和底部,于平扫T1WI均为等或低信号,T2WI为高信号,2例病变信号均匀,3例病变中可见囊变;增强扫描示病变轻度强化。结论:腺性膀胱炎易与膀胱癌混淆,MRI能清楚显示腺性膀胱炎的病变部位、范围、轮廓以及与邻近组织的关系,但无特异性,最后确诊需临床、影像和病理三者结合,病理检查是确诊的主要手段。

Objective：To study the clinical features and MRI findings of the cystitis glandularis （CG）. Methods jMRI findings, clinical and pathological manifestations of 5 cases of CG confirmed by pathology were retrospectively analyzed; relative literatures were also reviewed. Results：The major findings in these 5 cases were hematuria, dysuria and symptoms of urinary tract infection. The MR manifestations of CG in our 5 cases revealed that the lesions were predominantly sited at the neck and fundus of the urinary bladder and were shown isointense or hypointense signal intensity on plain Tl WI images and hyperintense signal intensity on plain T2WI images. In 2 of the 5 cases, heterogeneous signal intensity of the lesions was noted;in the lesions of the other 3 cases,cystic degeneration was found. On postcontrast scans,the lesions enhanced mildly. Conclusion：Cystitis glandularis was easy to be misdiagnosed as urinary bladder cancer. Although MRI provided the signs of location, size, contour and relationship with surroundings of the lesions, yet, all of those were non-specific. The definite diagnosis was primarily depended on the assessment of the imaging findings in combination with the clinical pictures and pathological features. Pathological examination of the lesion was the modality of choices for definite diagnosis.
