Idiopathic spinal cord herniation is a rare spinal cord disorder caused by spinal cord prolapse through a dural defect. Idiopathic spinal cord herniation usually occurs in the thoracic spine between the T4 and T7 vertebral levels. Neurological symptoms are slowly progressive and worsen over time, although timely diagnosis and treatment may enable reversal of symptoms. Clinical suspicion and magnetic resonance imaging lead to the diagnosis, with the latter demonstrating focal herniation of the spinal cord through an anterior dural defect. This report describes a patient with idiopathic spinal cord herniation diagnosed by magnetic resonance imaging and the literature about this rare entity.

特發性脊髓疝

特發性脊髓疝是一種罕見的脊髓疾病。脊髓經硬膜缺損疝出，好發於胸椎T4至T7之間的節段。該病的神經系統症狀為緩慢進行性，隨時間推移惡化；及時的診斷和治療可使症狀逆轉。如磁共振成像顯示出經前方硬膜缺損而形成的脊髓疝病灶，則臨床高度懷疑加磁共振成像可明確診斷。本文報告一名磁共振成像診斷的特發性脊髓疝病例，並回顧及討論文獻所記載的病例。
