Idiopathic spinal cord herniation is a rare but important and increasingly recognised cause of myelopathy seen in the thoracic spine. The factors that contribute to the aetiology of the condition and of the dural defect through which the cord herniates remain under debate. We discuss the clinical features and proposed pathophysiology of the condition, and illustrate key imaging findings on MRI, fluoroscopy and computed tomography (CT) myelography to establish the diagnosis, and discuss relevant differential diagnoses. Awareness and recognition of the condition is key as surgical intervention can improve outcomes for patients.
特发性脊髓疝是一种罕见但重要且日益被认识的胸段脊髓病变的原因。导致这种疾病的因素以及导致脊髓疝的硬脑膜缺陷的原因仍存在争议。我们讨论了这种疾病的临床特征和提出的病理生理学，并说明了 MRI、透视和计算机断层扫描（CT）脊髓造影的关键影像学发现，以确立诊断，并讨论了相关的鉴别诊断。对这种疾病的认识和认识是关键的，因为手术干预可以改善患者的预后。
