Intradural lumbar disc herniation is a rare disease. According to the reports of intradural lumbar disc herniations, most cases have developed as a chronic degenerative disc diseases. Traumatic intradural lumbar disc herniations are even rarer. A 52-year-old man visited our emergency center with numbness in his left calf and ankle after falling accident. Initial impression by radiologic findings was a spinal subdural hematoma at the L1 level. A follow up image two weeks later, however, did not demonstrate any interval change. The patient was decided to have an operation. In operative findings, a ruptured disc particle penetrating the ventral and dorsal dura was indentified after laminectomy. It was assumed to be a traumatic outcome not a degenerative change.
硬膜内腰椎间盘突出症是一种罕见疾病。根据硬膜内腰椎间盘突出症的报告，大多数病例是作为慢性退行性椎间盘疾病发展而来的。创伤性硬膜内腰椎间盘突出症更为罕见。一名52岁男性在摔倒事故后因左小腿和脚踝麻木前来我们的急诊中心就诊。根据影像学检查结果初步诊断为L1水平的脊髓硬膜下血肿。然而，两周后的后续影像检查未显示任何间隔期变化。决定对该患者进行手术。手术中发现，椎板切除术后发现一个破裂的椎间盘颗粒穿透了腹侧和背侧硬脑膜。推测这是创伤性结果而非退行性改变。
