摘要
目的 探讨动脉瘤样骨囊肿(ABC)的影像学特点及合理的治疗方法。方法分析了82例经手术病理证实的原发性ABC的影像学表现,对其中45例进行了为期3个月~24年的随访。结果ABC的X线平片常呈偏心膨胀性骨破坏,27例的CT成像中,21例可见液-液平面,11例出现钙化或骨化,7例核磁共振成像(MR)可见病变边缘为低信号环,其中6例在T2加权像可见多发不均匀的高信号囊腔及低信号的囊间隔,5例出现液-液平面。结论X线平片法简便,但对溶骨期和中轴骨病变限制较大。CT及MR对病变的范围和定性优于平片,对溶骨期ABC的诊断有帮助。刮除植骨术仍是四肢骨ABC有效的治疗方法,而动脉栓塞或栓塞加手术的方法对ABC的治疗有独特价值。
Objecitve To determine the imagimg features and useful therapeutic methods of aneurysmal bone cyst (ABG ) . Methods The radiographs , CT , and MR scans of 82 cases of pathologically proved ABC were retrospectively analyzed. Post-therapeutic follow-up of 45 cases was carried out for 3 months to 24 years. Results Plain radiographs showed eccentric expansile oateolysis in most cases. Fluid-fluid level was seen in 21 /27 cases on CT scans , and calcification or ossification in 11 /27 cases. MR images showed a hypointettse rim in 7 /7 cases , multilocular hyperintense cysts with hypointense septae on T2WI in 6 /7 cases , actd fluid-fluid levels in 5/ 7 cases. Conclusion CT and MR scans are superior to plain radio- graphs in the diagnosis of ABC in the osteolytic phase and in the axial skeleton. Curettage combined with bone graft surgery is the most effective therapeutic method for ABC of the extremities. Arterial embolization with or without surgery is valuble for the treatment of ABC arising from the axial skeleton .
