Abstract

The computed tomographic and magnetic resonance appearance of a calvarial aneurysmal bone cyst is described. Both forms of imaging demonstrate an epidural mass in the right occiput. The fluid-fluid levels in the mass on the T2-weighted images are characteristic of, though not specific for, aneurysmal bone cyst.

摘要

描述了颅骨动脉瘤样骨囊肿的计算机断层扫描和磁共振成像表现。两种成像形式均显示右枕部硬膜外肿块。T2加权图像上肿块内的液-液平面是动脉瘤样骨囊肿的特征性表现，但并非特异性表现。
