Abstract
本文报道口咽部外周型原始神经外胚层肿瘤1例。患者女,4岁,因“无明显诱因下出现言语含糊2年,睡时打鼾并逐渐加重伴睡时张口呼吸6 个月”就诊于绍兴市柯桥区妇幼保健院。CT平扫显示咽侧壁向咽腔内生长的不规则软组织肿块,密度不均匀,无钙化,增强扫描呈渐进性不均匀强化;MR平扫肿块呈T1WI等低信号、T2WI、DWI高信号,突向咽腔致相邻气道狭窄,肿块基底部边界欠清,增强扫描呈渐进性不均匀强化。病理检查诊断小圆蓝细胞性肿瘤,结合免疫组化及分子基因检测诊断外周型原始神经外胚层肿瘤。CT、MRI表现对诊断原始神经外胚层肿瘤有重要的参考意义。本例患者经部分消融+化疗术后,出院至今复查未见肿物增大,预后良好。.
