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.
