Pain in the sternum above the breast, not excluding mediastinal lesions, should be further examined by chest CT. Because some patients with mediastinal cysts gradually increase in size, they may also present with chest pain, and CT examinations can confirm the diagnosis and require further surgical options if necessary. In addition, patients with vascular diseases, especially aortic dilated aortic aneurysms, and patients with severe entrapment aneurysms, will have significant anterior chest pain, upper side of the breast, and patients will also have increased blood pressure, and ordinary pain medication cannot stop the pain, and further enhanced CT examination can confirm the diagnosis. Aortic aneurysms can be very dangerous if they rupture, so they should be treated actively after diagnosis, either by interventional therapy or open surgery. It is important to monitor blood pressure changes, as many patients are suffering from chronic hypertension. In addition, in young people, it can also be seen in congenital developmental abnormalities, commonly known as Marfan’s syndrome.
