摘要
目的:探讨动脉瘤样骨囊肿的影像特征,以提高诊断正确率。方法:综合分析经病理证实的19例动脉瘤样骨囊肿的影像表现,除常规X线检查外,11例另行CT检查,7例另行MRI检查。结果:囊肿发生于长管骨的13例、发生于扁骨及不规则骨的5例、发生于短管骨的1例,均于X线上表现为囊状膨胀性骨质破坏。其中11例见骨性分隔,CT表现为软组织密度,11例中4例见短小液-液平面,MRI除上述特点外,在显示液-液平面上更有优越性。结论:动脉瘤样骨囊肿的X线典型表现,结合CT及MRI显示的内部结构,尤其是对液-液平面的显示,可大大提高诊断正确率。
Objective To observe the manifestations of aneurismal bone cyst （ABC） to increase its diagnosis accuracy.Methods Totally 19 ABC patients confirmed pathologically underwent conventional X-ray examination, of which. 11 oues went through CT exanunation and 7 ones went through MRI examinalion. Results There were 13 ones with cysts in long bones. 5 ones with cysts in flat or irregular bones, and 1 ease with cyst in short bome. Cystie expanding bony destruction was found in the 19 patients. Totally 11 ones were found with bone separation, and soft tissue density by CT examination. of which. 4 ones had fluid-fluid levels. MRI gained advantages in displaying of fluid-fluid level. Conclusion The diagnosis accuraey of ABC can be enhanced greatly when its X-ray manifeslations are combined with displaying fluidfluid level with CT or MRI.
