摘要
目的探骨尤文氏肉瘤患者的影像学表现及其诊断价值。方法回顾性分析30例经穿刺病理证实的尤文氏肉瘤患者的X线、CT及MRI表现。结果 30例患者病变均发生于长管状骨干骺端及骨干。X线特点:30例患者均出现骨质硬化伴有局限骨质疏松;20例出现放射状骨膜反应;15例可见Codman三角及软组织肿块。CT表现:30例患者均出现骨髓腔内呈软组织密度,骨皮质局部呈溶骨性骨质破坏;20例患者可见骨膜新生骨呈葱皮样改变并可见放射状骨针。MRI信号特点:肿瘤在T1WI呈不均匀长T1信号,在T2WI呈不均匀长T2信号;20例患者可见骨膜新生骨,呈等T1短T2信号;放射状骨针呈长T1短T2信号;30例患者病灶周围软组织内均可见不均匀高低混杂信号,增强后30例患者病灶呈明显不均匀强化。结论 X线、CT及MRI对骨尤文氏肉瘤具有较高的临床诊断价值,三者综合应用可提高其诊断准确率。
Objective To investigate the imaging findings of patients with bone Ewing sarcoma and its diagnostic value. Methods The X-ray, CT and MRI manifestations of 30 patients with Ewing sarcoma were analyzed retrospectively. Results The lesions of 30 patients were occurred in the long tubular backbone epiphyseal end and backbone. X-ray features： 30 patients with a bone sclerosis limited osteoporosis; 20 patients with radial periosteum reaction; 15 patients of visible Codman triangle and soft tissue mass. CT manifestations： 30 patients in the bone marrow cavity in soft tissue density, bone cortex local were dissolved osseous bone destruction; 20 patients showed periosteal new bone in onion skin, radial spicule visible and change. MRI signal features ： the tumor uneven long T1 signal in TI WI, T2WI in the uneven long T2 signal; 20 patients showed periosteal new bone, a short T1 and T2 signal; radial spicule had short T1 and long T2 signal; visible in the surrounding soft tissues of 30 patients were not evenly mixed signals, 30 patients with lesions was significantly enhanced uneven reinforcement. Condusion The clinical diagnostic value of X-ray, CT and MRI technology are higher for Ewing sarcoma, comprehensive analysis of three imaging methods can improve the diagnostic accuracy.
