文档介绍：动脉瘤样骨囊肿的影像学分析
【】目的分析、探讨动脉瘤样骨囊肿(anuerysmal bone cyst,abc)的影像学特征及不同影像学检查方法的诊断价值,提高abc术前诊断正确率。方法回顾性分析11例经病理证实且资料完整的abc病人并结合文献资料,分析abc的各种影象学表现及其病理基础,总结abc较特征性的影像学征象。结果病变表现为囊状膨胀性骨质破坏10例,平片显示膨胀骨皮质呈线形包壳者4例,ct显示囊内纤维性或骨性间隔4例,密度不均呈多囊状,病变大部为液性低密度区3例,mr t2ri可从不同方面反映abc的影像学特征,三者结合可提高abc的术前诊断正确率。

[abstract] objective to investigate the image features of anuerysmal bone cyst (abc), and to evaluate the value of various imaging methods in the diagnosis of abc, and to improve the accuracy rate of preoperative diagnosis of abcs. methods eleven patients ed by pathology and full clinical data age and pathologic manifestations aging characteristics of abcs. results cystic expansive destruction of bone ages, the fibrous or osseous septa ainly lor images, the t2ostly uneven and presented cavernous appearances in 4 patients. conclusion abcs has characteristic imaging appearance. respectively, x-ray plain film,ct or mri plays different role in revieage feature of the abcs and the bination of these three imaging methods may improve the accuracy rate of preoperative diagnosis of abcs.
