摘要
目的:探讨小儿膀胱横纹肌肉瘤(rhabdomyosarcoma,RMS)的X线造影和CT表现特征,提高对本病的认识。方法:回顾性分析10例经手术病理证实的膀胱RMS的临床影像资料,全部病例均行静脉尿路造影和/或膀胱造影检查,其中4例行CT扫描。结果:造影显示膀胱内葡萄簇状充盈缺损8例,膀胱三角区大的分叶状充盈缺损影2例,6例膀胱壁毛糙。4例CT检查均显示膀胱腔内典型葡萄簇状低于腹壁肌肉密度软组织肿块,局部膀胱壁增厚,增强扫描病灶呈轻中度强化。结论:膀胱RMS影像表现具有一定特征,结合患儿年龄及临床特征多可做出正确诊断。
Objective：To study the cystography and CT features of bladder rhabdosareoma in children for further understanding of the disease. Methods：Clinical data and imaging findings in 10 cases of children with bladder rhabdosarcoma were retrospectively analyzed. All cases were taken intravenous urography or cystogram, and 4 cases were taken CT scan. Results： Botryoidalis filling defects were found in 8 cases, massive phylloid idling defects in 2 cases and rigid bladder in 2 cases in intravenous urography or cystogram. Botryoidalis shadow of low-musctdar density and thick-walled bladder were showed in CT scan, while, after the administration of contrast media, the ttanors were slightly or moderately enhanced. Conclusion：There are some certain radiographic characteristics in pediatric bladder rhabdosarcoma and we can make a correct diagnosis combining with clinical features.
