Abstract：Objective To explore the clinical characteristics and diagnosis points of idiopathic spinal cord herniation (ISCH), in order to improve the diagnosis. Methods A retrospective analysis was performed on clinical data of one misdiag-nosed case of ISCH. And the relevant literatures were reviewed. Results The middle-aged male patient was admitted to our hospital due to weakness in left lower limb for 2 years and aggregation for 1 year. He had been diagnosed and treated in many other hospitals but no clear diagnosis had been made and no effective treatment had been given. During the physical examina-tion in our hospital, incomplete transverse injury of spinal cord was found under umbilical plane given priority to the left side. Spinal MR imaging showed that T8 was bent and angulated deformed to the left of the ventral side, and the herniation was out of the left subdural mater, dorsal subarachnoid secondary enlargement, and no mass was around, and spinal cord herniation was suspected. Then surgery confirmed the patient as having ISCH. 4 weeks after operation, the muscles of double lower limbs apparently recovered, the muscle tone and the reflex returned to normal. Conclusion ISCH is rare in clinical practice. Brown-Sequard syndrome is common in early manifestation, which may easily be misdiagnosed. Early spinal MR examination contributes to diagnosis and identification of the disease.
