摘要

本研究收集了20個年齡介於25至70歲間，臨床上有持續性神經根疼痛的病例，運用電腦斷層掃描攝影，磁振造影，脊椎腔攝影及其後的電腦斷層掃描攝影來評估側位腰椎椎間盤的突出。病灶發生部位以L5-S1最多，佔70%。其中有4例同時合併有椎管內的椎間盤突出。由於電腦斷層掃描攝影和磁振造影可以很清楚的將椎間盤突出的範圍及有無脊椎腔或神經根的壓迫表現出來，因此對於側位椎間盤突出的診斷，電腦斷層掃描攝影和磁振造影優於脊椎腔攝影。

The purpose of this study is to determine the value in detecting lateral disc herniation (LDH) which was depicted by myelography, computed tomography and magnetic resonance imaging. We retrospectively reviewed 20 patients presenting LDH with persistent lumbar radiculopathy. Fourteen cases were evaluated with CT scan and 3 were evaluated by MRI and 6 cases were evaluated by lumbar myelography with post-myelographic CT. The most commonly affected level was L5-S1 (70%) in our series. This accounted for the majority of upper lumbar root compression syndromes. Myelography disclosed LDH in three cases presenting with obliteration of the corresponding nerve sheath. Epidural soft tissue lesion encroaching upon extraforaminal or neural foramen was seen 20/20 on CT scans and 2/3 on MRI respectively. Our experience suggests that CT and MRI are more effective than myelography for demonstrating the presence and extent of LDH.
