What Is Horner's Syndrome?

2. Causes of Horner’s Syndrome
Horner’s syndrome is usually the result or symptom of another issue in the body. More often than not, it occurs because a tumor or growth has formed within the chest, neck, or lungs. A Pancoast tumor is often to blame, which is a type of growth that develops in the upper part of the lungs. While the chest is one area where conditions can lead to Horner’s syndrome, the brain can also be the source. Any growth or lesion that develops along the stem of the brain or spinal cord could lead to it.
Some reports have pointed out that inflammation may lead to the development of Horner’s syndrome. When the lymph nodes become swollen due to overactivity, the inflammation can disrupt the pathways of the nervous system.
