Thoracic Syringomyelia in a Patient with Amyotrophic Lateral Sclerosis

摘要

We report a patient with bulbar-onset, clinically defined, sporadic amyotrophic lateral sclerosis bearing an isolated syringomyelia of the lower thoracic portion of the spinal cord. This is a very unusual association between two rare and progressive disorders, both affecting the spinal motoneurons. Syringomyelia might have acted as a phenotypic modifier in this ALS patient.
