Introduction

This disease can occur in any part of the cervical sympathetic pathway. It is extremely rare to be caused by central nervous system lesions above the first thoracic cord.

Cause

Cause

Almost all of this disease is caused by damage to the cervical sympathetic ganglia caused by neck trauma. During neck surgery, iatrogenic accidental damage to the sympathetic nerves in the neck and the sympathetic nerve bundles in the spinal cord. Tumors in the brachial plexus, cervical sympathetic ganglia, anterior mediastinal sinus, spinal cord, and hypothalamus are also considered to be the cause of this disease. Congenital dysplasia can also cause this disease.
