Syringomyelia is a neurological disorder that is caused by abnormal cerebrospinal fluid flow or circulation. It is an incidental finding in most cases, predominantly presenting with sensory symptoms of insensitivity to pain and temperature. Spinal ossified ligamentum flavum (OLF) leading to syringomyelia is one of the rare causes. The authors report an unusual case of syringomyelia due to a thoracic OLF.
A 54-year-old female presented with backache, difficulty walking, spasticity in the bilateral lower limbs, tingling sensation in the bilateral lower limbs, and paraparesis for 5 years. Her radiological investigations were suggestive of an OLF causing a syrinx. She underwent laminectomy, and her syrinx resolved on subsequent follow-up.
A syrinx due to a single-level OLF is rare, and this uncommon cause should be kept in mind while formulating treatment plans.
脊髓空洞症是一种由脑脊液流动或循环异常引起的神经系统疾病。在大多数情况下，它是偶然发现的，主要表现为对疼痛和温度不敏感的感觉症状。导致脊髓空洞症的脊柱黄韧带骨化（OLF）是罕见原因之一。作者报告了一例因胸段OLF导致的脊髓空洞症罕见病例。
一名54岁女性，出现背痛、行走困难、双侧下肢痉挛、双侧下肢刺痛感及双下肢轻瘫5年。她的影像学检查提示为OLF导致脊髓空洞形成。她接受了椎板切除术，随后随访中脊髓空洞消失。
由单节段OLF导致的脊髓空洞症很罕见，在制定治疗方案时应考虑到这种不常见的病因。
