摘　　要：目的分析和探讨腺性膀胱炎(cystitis glandularis,CG)的MR表现。方法分析本院膀胱镜活检术后病理诊断为腺性膀胱炎的患者13例,对其MR表现进行分析。结果 13例均行膀胱MR扫描,其中平扫7例,6例行增强扫描。13例CG的MR特征为:病灶多累及膀胱三角区、颈部及膀胱后壁(膀胱三角区3例,颈部3例,三角区和颈部均累及7例),输尿管开口受累时易造成开口狭窄并尿路积水(2例),MR平扫表现为膀胱腔内占位并邻近膀胱壁增厚病变(4例)、弥漫膀胱壁及粘膜增厚型病变(6例)、膀胱壁片状增厚型病变(3例),病变TIWI呈等信号,T2WI呈高于膀胱壁的高信号,DWI病灶呈稍高信号,ADC值平均约(1. 53±0. 12)×10^(-3)mm^2/s,范围(1. 34～1. 75)×10^(-3)mm^2/s,增强后病灶大多为轻度强化(5例),部分为明显强化(1例)。结论腺性膀胱炎的MR表现尤其是在DWI及ADC值、强化方式上,有助于和膀胱癌鉴别。Objective To analyze and investigate the appearance of MR imaging in cystitis glandularis.Methods The preoperative MR findings of 13 cases with cystitis glandularis which had been proved by pathology after the cystoscopy were analyzed retrospectively from 2015.6 to 2017.9.Results In 13 cases （male=12, female=1）, age ranged from 38 to 67 years, and the symptoms contained hematuria （n=4）, urinaty irritation symptoms （n=3）, dysiria （n=1）, and symptomless （occupation in urinary bladder in physical examination） （n=5）. All the cases had been operated by MR scanning, in which there were non-enhanced examinations （n=7）, enhanced examinations （n=6）. On the MR findings, the locations of cystitis glandularis were trigone of bladder （n=3）, bladder neck （n=3）, or trigone and neck of bladder （n=7）, and in which there were 2 cases with urinary hydronephrosis as the ureteral orifice had been invasived by cystitis glandularis. On the non enhanced MR imaging, the features of CG can be classified as nodular thickening （n=4）, thickening （n=6） and limited thickening （n=3） of the bladder wall with iso-intensity signal of T 1WI, hyper-intensity on T 2WI, slight hyper-intensity on DWI, iso-or slight hypo-ingtesity on the corresponding ADC maps with average ADC value （1.53±0.12）×10^-3 mm^2/s range （1.34-1.75）×10^-3 mm^2/s. After enhancement, the lesions showed slightly enhancement （n=5） and obvious enhancement （n=1）.Conclusion MR features of CG have some certain characteristics, especially on DWI, ADC value, and enhanced patterns, which could be helpful to be deferential diagnosis of carcinoma.
