1、儿童浅表器官结外淋巴瘤的超声诊断及病理特征分析[摘要]冃的探讨儿童浅表器官结外淋巴瘤的超声及大体病理特征。方法冋顾性分析深圳市儿童医院2007年9刀〜2016年6刀收治的16例经手术病理证实的儿童浅表器官结外淋巴瘤的超声及病理特征。结果16例中,非霍奇金淋巴瘤11例,霍奇金淋巴瘤5例。儿童浅表器官结外淋巴瘤超声表现为肿块型6例,弥漫型10例。6例肿块型表现为低回声团块或极低回声团块,边界欠清,形态不规则、呈分叶状,后方冋声可增强,内冋声不均匀,内部均未见液性无冋声,罕见钙化强回声,CDFI可显示
2、病灶内血流信号丰富。10例弥漫型表现为实质脏器弥漫性增大,内凹声减低、不均匀,其内显示散在极低回声区,无明显液性无回声及钙化强回声,CDFI显示实质脏器血流信号丰富,低回声团内显示点、条状血流信号。结论儿童浅表器官结外淋巴瘤有较典型的超声特征,超声在淋巴瘤的诊断中可以提供有价值的诊断信息。[关键词]浅表器官;结外淋巴瘤;超声;儿童;病理[中图分类号]R725.5[文献标识码]A[文章编号]1674-4721(2017)06(a)-0120-04[AbstractJObjectiveToexplo
