摘　　要：目的　探讨动脉瘤样骨囊肿的影像学表现及诊断作用。方法　回顾性分析了经病理证实的 13例动脉瘤样骨囊肿的X线胶片表现 ,其中 4例同时做了CT检查 ,血管造影及核素扫描各 1例。结果　动脉瘤样骨囊肿的发病年龄多在 2 0岁以下 (77% ) ,X线胶片表现为偏心性 (10例 )或中心性 (3例 )溶骨性病灶 ,大部分位于长骨干骺端 (8例 )。典型者表现为膨胀性”气球样”改变。典型CT表现为病灶内出现液 -液平面。血管造影显示病灶周围有丰富的血管 ,中心血管相对较少。核素扫描显示病灶放射性核素摄取率增加 ,其分布与血管造影的血管分布一致。结论　综合分析X线胶片、CT、血管造影及核素扫描的表现可提高动脉瘤样骨囊肿的诊断准确率 。Objective To evaluate the imaging features of aneurysmal bone cyst (ABC).Methods 13 cases of ABC proved by surgery and pathology were studied retrospectively.The patients were studied by using ragiography(13cases),CT(5cases),DSA(1case) and nuclid scintiscanning (1case).Results The patients with ABC were mostly under the age of twenty.Plain film demonstrated excentric or central obsteolytic lesion,which was mostly at the metaphsis of long bons.“Balloon-like”expansive lesion was their typical X-ray apperance,and“fulid-fulid level”(FFL) was their typical apperance shown on CT.DSA showed that vessels were rich around the lesion,but less in the central area relatively.Nuclide scintiscanning showed a increasing in take in the lesion which had the same distribution as the vessels were on DSA.Conclusion ABC diagnosis rate could be raised by analysing the appearances on plain film,CT,DSA and Nuclide scintiscanning,but definit diagnosis rely on pathologic examination.
