This study compares the value of sonography and computed tomography (CT) in assessing fluid-fluid levels (FFLs) in aneurysmal bone cysts (ABCs) in children.
Five children 4-13 years old with ABC in pubis, humerus, fibula, calcaneus, and ilium-ischium were studied between January 1995 and December 1996. Plain radiography, sonography, and CT were performed.
FFLs were visualized equally or better with sonography than with CT.
We propose that sonography be used to complement plain radiography in the prebiopsy assessment of expansile bone lesions with cortical bone thinning because the presence of FFLs is characteristic of ABC. CT and/or magnetic resonance imaging could be used in indeterminate cases and in complex anatomic locations. Such an approach would save time and reduce costs and discomfort to children.
本研究比较超声检查和计算机断层扫描（CT）在评估儿童动脉瘤样骨囊肿（ABC）中液-液平面（FFL）的价值。
1995年1月至1996年12月期间，对5例年龄在4至13岁、分别发生于耻骨、肱骨、腓骨、跟骨以及髂骨-坐骨的ABC患儿进行了研究。进行了X线平片、超声检查和CT检查。
超声检查显示FFL的效果与CT相同或更好。
我们建议，在对伴有皮质骨变薄的膨胀性骨病变进行活检前评估时，超声检查可用于补充X线平片检查，因为FFL的存在是ABC的特征。对于不明确的病例和复杂的解剖部位，可使用CT和/或磁共振成像。这样的方法将节省时间，并降低成本以及减少患儿的不适。
