Abstract
We present a 75-year-old man who, for 2 weeks, had progressive pain in both of his thighs when standing straight. MR imaging showed a sequestrated disk fragment, which had a signal intensity similar to that of a herniated disk with a rim enhancement in the posterior epidural space and a ruptured outermost annulus of the intervertebral disk at L2-3. Awareness of these MR imaging findings can help in the diagnosis of posterior epidural disk migration.
摘要
我们报告一名75岁男性，他在站直时双侧大腿渐进性疼痛2周。磁共振成像显示一个游离椎间盘碎片，其信号强度与突出椎间盘相似，在后硬膜外间隙有边缘强化，且L2-3椎间盘最外层纤维环破裂。认识到这些磁共振成像表现有助于诊断后硬膜外椎间盘移位。
