The Brown-Séquard Syndrome

In recent years the name of Brown-Séquard has been assigned to syndromes caused by spinal cord damage differing widely in extension. On the basis of a review of more than 600 published cases, we propose that Brown-Séquard-plus syndromes be distinguished from the pure Brown-Séquard syndrome. This distinction is shown to be justified on clinical, anatomic, and historical grounds. Two case histories are reported herein to illustrate the essential differences between these syndromes.
