Abstract

Cauda equina syndrome is a surgical emergency caused by the compression of the lumbosacral nerves. The most frequent cause is discal herniation, while tumoral pathology in this region is rare, and congenital processes are less common. We report the case of a young 37-year-old male patient, admitted to the emergency room with an incomplete cauda equina syndrome. As medical history, a lumbar surgery 15 years ago was reported with no documentation. An MRI was performed, revealing a mass within the filum terminal exhibiting three components suggestive of a dermoid cyst accompanying a split cord malformation, which was confirmed by pathology. Various disorders may be associated to intradural dermoid cyst, such as lipoma, low-lying cord, hydromyelia or thick filum. Surgery is the treatment of choice, and MRI plays a crucial role in detecting associated abnormalities and determining surgery priorities.
不完全性马尾综合征的不寻常病因:伴有脊髓分裂畸形的皮样囊肿病例报告
马尾综合征是一种因腰骶部神经受压而引起的外科急症。最常见的病因是椎间盘突出症,而该区域的肿瘤病变很少见,先天性病变也不常见。我们报告了一例 37 岁男性患者的病例,他因不完全马尾综合征被送入急诊室。病史显示,患者 15 年前曾做过腰椎手术,但没有任何记录。经磁共振成像检查,发现在丝状端内有一个肿块,有三个组成部分,提示为伴有脊髓劈裂畸形的蝶形囊肿,病理证实了这一点。硬膜内蝶形囊肿可能与多种疾病有关,如脂肪瘤、低位脊髓、髓鞘积水或厚丝状物。手术是首选治疗方法,而磁共振成像在检测相关异常和确定手术优先顺序方面起着至关重要的作用。
