目的：提高对不规则骨原发性动脉瘤样骨囊肿影像学表现的认识。方法回顾性分析经手术病理证实的29例骨原发性动脉瘤样骨囊肿的影像表现。其中9例发生于不规则骨，20例发生于规则骨。结果29例原发性动脉瘤样骨囊肿主要影像表现：1、皂泡状或吹气球样膨胀性骨质破坏：平片7例，CT 18例，MRI 19例；2、病灶内骨间隔及骨脊：平片3例, CT 7例； MRI 3例；3、病灶周围骨或纤维组织硬化：平片0例, CT 3例, MRI表现为病灶周围线状低信号影15例；4、骨壳部分断缺：平片2例,CT 5例, MRI 3例；5、液-液平面： CT 2例，MRI 20例；6、骨膜反应：无；7、软组织肿块：CT 0例，MRI 1例。结论不规则骨原发性动脉瘤样骨囊肿与常见部位ABC影像学特征大致相仿，多层螺旋CT与MRI综合分析更有助于ABC术前诊断。

Objective To improve imaging diagnosis of aneurysmal bone cyst at rare parts bone. Methods 29 cases with aneurysmal bone cyst confirmed by surgery and pathology were analyzed retrospectively. Of the 29 cases,9 cases occurred in irregular bone,5 cases of occipital,2 case of pubic, 2 case of sacrum.;20 cases occurred in regular bone, 11 case for humerus,9 case for femur. Results The major imaging signs of the 29 cases of aneurysmal bone cyst located at flat bone and irregular bone were:1、Soap bubble-like expensive bone destruction was detected by X-ray in 7 cases, by CT in 18 cases, and by MRI in 19 cases; 2、Bone trabeculae mixed with osseousseptae in the lesion were detected by X-ray in 3 cases, by CT in 7 cases, and by MRI in 3 cases;3、Local sclerosis of the bony structure adjacent to the lesion was detected by X-ray in 0 cases, by CT in 3 cases, and by MRI in 15 cases;4、Partial pathologic fractures of bone shells were detected by X-ray in 2 cases;by CT in 5 cases, and by MRI in 1 cases;5、Fluid-fluid level inside the lesion was detected by CT in 2 cases, by MRI in 20 cases; 6、No periosteal reaction; 7、Soft tissue mass was detected by CT in 0 case, by MRI in 1 case. Conclusion The imaging characteristics of aneurysmal bone cyst at flat bone and irregular bone are similar to that at long-tubular bone, DSCT and MRI can distinctly improve the correct rate of diagnosis.
