摘要
本文报道21例经脊髓腔碘油造影或手术证实的脊髓粘连性蛛网膜炎。病变常以脊神经根刺激症状为首发症状,但由于蛛网膜的纤维粘连和/或囊肿直接压迫脊髓,或使供应脊髓的动脉受压及脊髓静脉回流困难,常致脊髓缺血、水肿甚至空洞形成,及至病人就诊时其临床表现多为髓内病征。脊髓腔碘油造影目前仍为主要的确诊手段,主要表现为蛛网膜下腔部分或完全梗阻,或造影剂呈“蜡泪”状,或造影剂梗阻平面与临床定位平面不尽相符等。磁共振成像(MRI)有助于局限性粘连与肿瘤的鉴别。
Twenty one cases of the spinal adhesive arachnoiditis verified with myelogra-phy and/or operation were reported. Irritative symptoms on the radicula was usua-lly the first symptom, but intramedullary signs might be the main ones causingthe patient to seek for medical advice. The reasons were that the spinal cordwas compressed by arachnoid fibers, consequently making the spinal vein reflowdifficult. Ischemia and edema of the spinal cord and even syringomyelia formationmight be the result. So far myelography has been considered to be the virtualdiagnostic means. Not only narrowing or obstruction of the subarachnoid spacecould be visualized but also arachnoid cyst, and the level of the blockage. MRI wasuseful in distinguishing between local adhesion and tumor.
