摘要
目的:探讨小儿膀胱横纹肌肉瘤(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16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?蛐或膀胱造影检查,其中6例行CT扫描。结果:造影显示葡萄簇状充盈缺损13例;膀胱三角区大的分叶状充盈缺损影3例,6例膀胱壁毛糙。6例CT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,膀胱壁增厚,增强呈轻中度强化。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。
Abstract
Objective: To study the cystography and CT features of bladder rhabdomyosarcoma in children for further understanding the disease. Materials and Methods: Clinical data and imaging findings in 16 cases with bladder rhabdomyosarcoma were retrospectively analyzed. All cases had intravenous urography or cystogram, and 6 cases had CT scan. Results: Botryoidal filling defects were found in 13 cases, massive phylloid filling defects in 3 cases and rigid bladder in 6 cases in intravenous urography or cystogram. Botryoidal shadow of low-muscular density and thick-walled bladder were showed on CT scan while after the administration of contrast media the tumors were mildly or moderately enhanced. Conclusions: There are some certain radiographic characteristics in pediatric bladder rhabdomyosarcoma, we can make a correct diagnosis combining with clinical features.
