Causes Of Horner Syndrome
Thoracic Aortic Aneurysm

A thoracic aortic aneurysm occurs when an area in the upper part of the aorta, located in the chest, is weakened and balloons in size. Patients with this condition may not experience any symptoms if the aneurysm is small. Larger aneurysms could produce symptoms such as back pain, coughing, hoarseness, chest pain, and shortness of breath. Thoracic aortic aneurysms are often discovered during routine imaging studies conducted for another reason. For example, they may be detected if the patient has a chest x-ray, echocardiogram, CT scan, or MRI scan.
To treat small aneurysms, doctors may choose to regularly monitor their growth with frequent scans. Surgery might be suggested for aneurysms larger than 1.9 inches. Sometimes, an aneurysm could rupture, leading to potentially life-threatening complications. Possible signs of a ruptured aneurysm could include swallowing difficulties, sudden and intense chest or back pain, low blood pressure, breathing difficulties, and weakness along one side of the body. Emergency medical care should be sought for patients with these symptoms, and emergency surgery may be required.
Thyroid Carcinoma

A thyroid carcinoma is a tumor that forms on the thyroid gland. Patients with a thyroid carcinoma could experience hoarseness in the voice, and they might also notice a lump at the front of the neck. Swallowing difficulties, pain in the neck and throat, and swollen lymph nodes in the neck may be observed. To diagnose this condition, clinicians will palpate the thyroid to check for enlargement or other physical changes. Patients will have blood tests to look for any abnormalities in thyroid function, and a thyroid tissue sample may be biopsied.
Ultrasounds, CT scans, and PET scans could be ordered to help the healthcare team determine if the carcinoma has spread to areas outside the thyroid. The majority of patients with thyroid carcinoma will have an operation to remove all or part of their thyroid gland. Lymph nodes in the neck might need to be removed as well, and some patients may need radiation or chemotherapy.
