摘　　要：目的探讨血管畸形和血管中间性肿瘤的影像鉴别诊断。方法回顾性分析58例血管畸形和血管中间性肿瘤患者的影像表现。结果血管畸形42例,CT与MRI显示病变边缘均呈不规则形,边界清晰,CT与X线显示5例病变对邻近骨质产生压迫改变。31例MRI中,T2WI3例呈较高信号(接近脂肪信号),28例呈混杂高信号(高于脂肪信号),其中20例在病变区显示圆形血管样高信号。血管中间性肿瘤16例,CT与MRI显示7例肿块呈类圆形,边界规则,8例肿块呈分叶状,1例边缘呈"蟹爪"状,5例瘤周可见水肿和占位效应,CT与X线显示3例周围骨质产生侵蚀改变,2例肿瘤在骨内可形成溶骨性破坏。11例MRI中,T2WI11例呈较高信号。结论血管畸形和血管中间性肿瘤影像表现不同。Objective To explore the imaging differential diagnosis of vascular malformations and intermediary character hemangiomas. Methods The roentgenographic,CT and MRI findings of vascular malformations and intermediary character hemangiomas in 58 cases were analysed retrospectively. Results In 42 cases with vascular malformations, the lesions were irregular with definite margins, and 5 cases showed the bone compressed adjacent to the lesions. 31 patients studied with MRI ,3 cases appeared as hyperintensity（ equal to fat） and 28 cases appeared as mixed hyperintensity（ higher than that of fat） on T2WI,20 cases showed circular markedly vessel -like hyperintensity on T2WI . In 16 cases with intermediary character hemangiomas,7 cases showed circular soft tissue masses, the masses were lobulated in 8 cases and ＂crab nail＂ in 1 case,5 cases showed edema of around the tumors and occupying effect on CT and MRI,3 cases showed bone corroded adjacent to the lesions,2 cases showed bony destruction. Of the 11 patients studied with MRI, the lesions showed hyperintensity on TEWI. Conclusion The imaging findings of vascular malformations and intermediary character hemangiomas are different.
