摘　　要：目的总结胸部Askin瘤的影像表现,提高对该病影像征象的认识,减少误诊。方法报道3例经病理确诊为胸部Askin瘤的临床及影像表现,并复习相关文献。结果1例显示右侧锁骨区稍高密度软组织影,边界模糊。2例显示胸腔巨大软组织肿块影。胸部CT显示1例位于右侧胸壁上,两例位于右侧胸腔。平扫均呈等密度,未见钙化影。增强后均可见明显不均匀强化,肿块内可见明显坏死区。3例病灶均可见肿瘤血管影。病灶与周围组织分界尚清晰,瘤肺界面清晰。结论胸壁Askin瘤CT上有明显恶性肿瘤表现,在儿童或青少年的胸部肿瘤中需要考虑到该诊断,确诊还需要病理。Objective To summarize the imaging performance of chest Askin's tumor,raise the awareness of imaging signs of the disease,and reduce misdiagnosis.Methods To report 3 cases of clinical and imaging images of Askin tumor diagnosed by pathology,and review related literature.Results One case showed as a slightly high-density soft tissue in the right clavicular region with blurred boundaries.Two cases showed as a large soft tissue mass in the chest.Chest CT showed 1 case on the right chest wall and 2 cases on the right chest thoracic cavity.Plain scans of the lesions were of isointense density without calcification.After enhancement,significant non-uniform enhancement was seen,and necrosis was evident within the mass.Tumor vasculature was seen in all 3 lesions.The boundary between lesion and surrounding tissue is clear,the same as the interface between tumor and lung.Conclusion The chest wall Askin's tumor has obvious manifestations of malignant tumors on CT and the diagnosis needs to be taken into account in children or adolescents with thoracic tumors.Pathological diagnosis is also needed.
