小儿盆腔及泌尿生殖系统横纹肌肉瘤超声诊断及病理分析

目的:探讨超声检查在儿童盆腔及泌尿生殖系统横纹肌肉瘤的诊断价值及病理类型分析.方法:对30例原发盆腔及泌尿生殖系统横纹肌肉瘤的超声检查结果结合病理类型进行分析.结果:膀胱横纹肌肉瘤11例,1例为葡萄簇型,其余10例均为胚胎性.前列腺横纹肌肉瘤3例,3例病理结果均为胚胎性.阴道横纹肌肉瘤1例,病理结果为葡萄簇型.盆腔横纹肌肉瘤15例,2例为腺泡状,其余13例均为胚胎性.本组盆腔及泌尿生殖系统横纹肌肉瘤超声基本表现为肿瘤边缘清楚,无包膜回声,形态规则或不规则形,内部为基本均质的低回声,部分肿瘤内部可见液化坏死.结论:超声检查可作为盆腔及泌尿生殖系统横纹肌肉瘤影像学检查的首选方法.

Diagnosis of Genitourinary and Pelvic Rhabdomyosarcoma in Children by Sonography and with Pathological Analysis

Purpose: To evaluate the value of sonography in diagnosis of children’s genitourinary and pelvic rhabdomyosarcoma(RMS).Methods: Thirty cases of genitourinary and pelvic rhabdomyosarcomas examed by sonography and proved by pathology exam were reviewed.Results: Of 30 cases,11 cases arose from the bladder,the pathological results of them were botryoid in 1 and embryonal in 10;3 cases from the prostate,the pathological results were embryonal;1 from vagina,the pathological result was botryoid;15 cases from pelvic,the pathological results were alveolar in 2 and embryonal in 13.The general manifestations of these 30 cases showed that the masses were with clear margin,no capsule,in regular or irregular shape,with homogeneous hypoecho and internal necrosis.Conclusion: Sonography exam could be the first imaging choice for the diagnosis of genitourinary and pelvic rhabdomyosarcoma.
