图1 右侧臂丛神经及颈部软组织浸润髓系肉瘤常规超声表现。图a、b 示右颈部前、中斜角肌,颈长肌,头长肌弥漫性增厚,局部呈包块状,回声减低不均,肌纹理结构不清,与周围组织分界欠清;图c、d 示臂丛神经不均匀肿胀,外膜结构尚清;图e、f 示肌层血供弥漫性稍增多
图2 右侧臂丛神经及颈部软组织浸润髓系肉瘤超声造影表现。右侧颈部病灶呈快速增强,快速廓清
图3 髓系肉瘤患者正电子发射计算机断层扫描表现。图a、b、c 示同层面横断面正电子发射断层(PET)图像、计算机断层(CT)图像、PET 和CT 融合图像示右侧颈部C5/6 椎间孔水平软组织密度肿物,与肌肉分界不清,延伸至椎管内,代谢活性增高,最大标准摄取值为11.7;图d 全身最大密度投影(MIP)示右侧颈部C3 ~T2 椎体水平肿物,与多发椎间孔关系密切,代谢活性不均匀增高
图4 髓系肉瘤病理图像。图a(HE×100)、图b(HE×400)示横纹肌组织内见肿瘤性小圆细胞弥漫浸润,部分细胞胞浆偏位;图c 免疫组织化学检测显示MPO(+)(×400);图d 免疫组织化学检测显示CD34(+)(×400)
