摘要
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,MRT2WI显示病变内部信号极不均匀呈海绵状液性信号4例。结论ABC有较特征性的影像学表现,平片、CT、MRI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。
Objective To investigate theimage features of anuerysmal bone cyst （ABC）, andto evaluate the value Of various imaging methods in the diagnosis of ABC, and to improve the accuracy rate of preoperative diagnosis ofABCs. Methods Eleven patients with ABCs confirmed by pathology and full clinical data were studied retrospectively; The various image and pathologic manifestations were studied carefully in order to find the imaging characteristics of ABCs. Results Cystic expansive destruction of bone were found in 10 patients, On CT images, the fibrous or osseous septa were showed in the lesion in 4 patients, mainly low density area in the lesion in 3 patients. On MR images, the T2WI signals were mostly 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 reviewing the image feature of the ABCs and the combination of these three imaging methods may improve the accuracy rate of preoperative diagnosis of ABCs.
