[Progressive Brown-Sequard syndrome secondary to idiopathic spinal cord herniation: clinico-radiological and surgical correlations].

INTRODUCTION

Idiopathic medullary herniation is an infrequent disease, which shows up in clinical form as a progressive mielopathy, most commonly known as the Brown-Sequard syndrome. Its anatomical base is a dural defect where a portion of anterior spinal cord gets progressively incarcerated. The MRI and myelo-CT scan show a bending of the spinal cord in the form of a «bell tent» towards the anterior dural sheath at the mid-dorsal portion mainly.

CASE REPORT: A 37 year old male, who was diagnosed of idiopathic medullary herniation and surgically treated by our own developed technique, reporting its neuroradiological, anatomo-surgical and clinical correlation.

CONCLUSION

Treatment should be individualized, as no standard surgical technique has been established up to the present.
