摘要 目的:评价影像学检查对动脉瘤样骨囊肿的诊断价值。方法:对22例经手术病理证实的动脉瘤样骨囊肿的影像学表现进行回顾性分析。22例均摄了平片,CT检查8例、MRI检查5例、DSA检查1例。结果:22例动脉瘤样骨囊肿发生于长管状骨16例,脊柱3例,骨盆2例,跖骨1例。平片和CT多表现为偏心膨胀性骨破坏,CT常可显示骨性分隔及液一液平面,MRI检查多表现为多囊长T1、长T2信号特点,CT和MRI检查13例中有4例出现液一液平面。DSA表现实质期可见中等量肿瘤染色。结论:动脉瘤样骨囊肿具有一定的影像学特征,CT特别是MRI对动脉瘤样骨囊肿诊断较平片有优势,综合影像学检查能提高动脉瘤样骨囊肿诊断符合率。
