摘要
分析8例Askin瘤的影像征象。材料和方法：回顾性分析8例Askin瘤的胸部平片、B超和CT资料。年龄13—62岁，平均29．8岁。全组均拍摄正侧位胸片和CT扫描，6例胸壁肿瘤行B超检查。全组均经病理组织学和免疫组织化学检查证实。结果：6例原发于胸壁软组织，肿瘤较小（平均大小3cm），术后半数近期复发，复发灶平均大小为5．5cm。2例原发于纵隔，肿瘤平均大小为7cm。瘤实质主要为软组织，散在液化、坏死或出血。CT增强后扫描呈不规则强化。5例受累胸膜表现为不规则状、结节状增厚。结论：Askin瘤典型影像表现为胸壁、胸膜和纵隔病灶相互融合成巨大肿块。因此，面对青少年患者的胸部软组织肿瘤，鉴别诊断时应考虑到Askin肿瘤。
Purpose： We present the imaging features in eight patient with Askin tumor. Materials and Methods： There was a retrospective analysis of the imaging results from 8 patients with askin tumor. The average age was 29.8 years （ranging from 13 to 62 years）. At diagnosis, all patients underwent chest CT, chest X - ray （CXR） and. Six had US. The diagnoses were confirmed histologically and immunohistochemically （n = 8）. Results： The tumous were originated in soft tissues of chest wall in six debutant patients, The tumors were mainly small （mean size： 3 cm）. After surgery from 1 to 3 month, half of tumors were recurred, which were large （mean size： 5.5 cin） . There were mediastinal involvement in two cases, the tumors were large （mean size： 7 cm） . All tumors were irregular, heterogeneous, had hemorrhage or necrosis and had variable contrast enhancement on CT. Five patients showed pleural nodular irregular involvement with direct infiltration of mediastinum and adjacent rib and muscle. Conclusion： Askin tumor typically manifest as large tumors involving mediastinium the chest wall and pleura. The askin tumor should be included in the differential diagnosis on aggressive soft tissue tumors in young patients.
