腺性膀胱炎的CT诊断

CT diagnosis of cystitis glandularis

目的探讨腺性膀胱炎(CG)的CT表现,提高其CT诊断水平。方法回顾分析10例经手术病理证实的CG患者的CT检查资料,均行多层螺旋CT平扫,其中9例同时行增强扫描。结果10例CG中CT表现为膀胱颈部和三角区7例,右前壁1例,累及整个膀胱壁2例。8例CT平扫表现为膀胱壁局限性增厚或呈结节状、扁丘状突向膀胱腔内的软组织密度影,大小1.0cm×0.8cm～4.3cm×5.9cm,2例膀胱壁弥漫性增厚,边缘光整。2例病灶内可见囊性低密度区。9例膀胱外壁光滑。平扫CT值17～49Hu,平均35Hu,增强扫描病变无明显强化或呈轻度不规则强化或环形强化,CT值30～80Hu,平均62Hu。结论CG多发生在膀胱颈部和三角区,螺旋CT能清楚的显示病变部位、大小、形态、密度、强化特点和周围组织的关系,在CG诊断和鉴别中有重要价值。

Objective To investigate the CT manifestations of cystitis glandular （CG）, and to improve the level of CT in diagnosing the disease. Methods The CT manifestations of 10 cases with CG which were proved by pathology were analyzed retrospectively. All the 10 cases performed multi-slice spiral CT plain scan, and 9 cases performed both CT pain and enhance scan. Results CT displayed the lesions located in the bladder neck and triangle area in 7 cases, in the right anterior wall in 1 cases, involve the entire bladder wall in 2 cases. Eight cases showed the local thickening or nodular or fiat dune-like shape thickening of the bladder wall, the size of the lesions were 1.0cm × 0.8cm - 4.3cm × 5.9cm, two cases showed the diffuse thickening of the bladder wall. Cystal low density were demonstrated in 2 lesions. The bladder exine were smooth in 9 cases. The CT value of the lesions were 17-49Hu （average 35Hu） on plain scans, the lesions showed no enhancement or slight inhomogeneous or circular enhancement after intravenous contrast administration and the CT value were 30-80Hu（average 62Hu）. Conclusion CG often occur in the bladder neck and trigone area, CT could demonstrate the location, size, shape, density, enhance feature and adjacent structure of CG, which has great value in the diagnosis and differential diagnosis of CG.
