1、中国临床医学影像杂志2015年第26卷第7期JChinClinMedImaging,2015,Vo1.26,No.7·469·儿童胸膜肺母细胞瘤的影像学表现及临床病理分析胡悦林,刘鸿圣,高秋,黄莉,鹿连伟,肖伟强,周宁(广州市妇女儿童医疗中心,广东广州510623)【摘要】目的:探讨儿童胸膜肺母细胞瘤(PPB)的影像学及临床病理表现,提高对本病的认识。方法:回顾性分析经手术病理及免疫组化证实的12例PPB的影像学资料,根据病理切片、免疫组织化学按Dehner分型分为I、Ⅱ、Ⅲ三型;根据不同分型的X线和CT特点,将影像表现与病理进行对照分析。结果:PPBX线表现为胸腔内
2、巨大占位病变,肺及纵隔结构受压。CT表现:胸膜下肺外围非均匀性巨大软组织肿块,常伴有胸腔积液、肺不张。增强扫描肿瘤实性成分呈不均匀明显强化,囊性成分无强化。镜检:肿瘤主要由原始胚胎性的圆形或卵圆形细胞组成。免疫组化:Vimentin(+),Desmin(+)。结论:PPB影像学表现不典型.确诊需依靠病理及免疫组织化学检验相结合。【关键词】肺肿瘤;儿童;体层摄影术,螺旋计算机[中图分类号】R743.2;R743.3;R814.42【文献标识码】A【文章编号】1008—1062(2015)07—0469—04Imagingfeaturesandclinicalpathol
