In spinal surgery, malformations of lumbar nerve roots and their coverings may result in difficult or even faulty differential diagnoses and intraoperatively in surgical peculiarities and problems. In 5000 operations of the lumbar spine carried out within a ten-year period, 35 cases of malformation of the lumbar nerve roots were observed with 17 conjoined nerve roots emerging from the dural sac and 18 perineurial cysts in the form of cystic anomalies in the transition area of dural and arachnoid root sac into the perineurium of the spinal nerve. Due to the experience gained from these operations carried out to date, radiologic findings as to imaging as well as their interpretation, indications for surgery and intraoperative management are being discussed.
在脊柱外科手术中，腰神经根及其被膜的畸形可能导致鉴别诊断困难甚至错误，在手术中也会出现手术特点和问题。在十年内进行的5000例腰椎手术中，观察到35例腰神经根畸形，其中17例神经根联合自硬膜囊发出，18例为神经束膜囊肿，表现为硬膜和蛛网膜根囊过渡区至脊神经神经束膜的囊性异常。基于迄今为止这些手术所获得的经验，本文将讨论影像学检查结果及其解读、手术适应证和术中处理。
