MRI Appearance of Lumbosacral Spine in a Patient with Ankylosing Spondylitis and Cauda Equina Syndrome

長期僵直性脊椎炎病患併發馬尾症候群在腰薦椎之磁振造影表現:病例報告

摘要


馬尾症候群是僵直性脊椎炎病患一個少見之併發症,我們在此提出一病例報告:一名68歲女性病患患有長期之僵直性脊椎炎併發馬尾症候群,其腰薦椎之磁振造影顯示具特徵性之硬膜囊擴張及許多的背側硬膜憩室。磁振造影為一強而有力又不具侵犯性之工具,不僅可以幫助確立診斷並且可以排除可治療之壓迫性病兆。脊髓腔X光攝影術對於此種病患可能難以施行,並且可能造成病人的傷害,故應避免。

並列摘要


Cauda equina syndrome is an unusual complication of ankylosing spondylitis. We present a case of a 68-year-old woman with long-standing ankylosing spondylitis who developed cauda equina syndrome. MRI revealed a characteristic widening of the lumbosacral thecal sac and numerous dorsal thecal diverticula. MRI is a powerful, noninvasive tool to confirm the diagnosis and exclude a treatable compressive lesion and provides a good alternative to myelography, an invasive and potentially dangerous procedure in such patients.
