Abstract
Key findings that aid in the diagnosis of an aneurysmal bone cyst are: 1) typically the patients are young individuals less than 20 years old; 2) an expansile bone lesion is bordered by a thin, low signal intensity rim mass; 3) the lesion is inhomogenously increased in signal on T2-weighted images; and 4) multiple fluid-fluid levels are seen with the mass on T2-weighted magnetic resonance imaging scans.
摘要
有助于诊断骨动脉瘤样囊肿的关键发现包括
1）患者通常为20岁以下的年轻人；2）膨胀性骨病变由薄的低信号强度边缘肿块包绕；3）病变在T2加权图像上信号不均匀增加；4）在T2加权磁共振成像扫描中可见肿块内有多个液-液平面。
