Aortic hemangiomas are generally more serious, but the severity depends on the specific location, size and shape of the tumor. Aortic hemangiomas are benign tumors that do not present serious life-threatening conditions, so they should be monitored or treated regularly according to the doctor’s advice. In some more important parts, such as cerebral hemangioma, located in the brain, the situation is relatively more critical, once the blood pressure rises, blood vessel wall thinning or other factors cause the tumor rupture may lead to paralysis, and sometimes even life-threatening, and need to be treated in time. For other hemangiomas which are smaller in size and not so important in relative location, they can be observed regularly according to the doctor’s advice.
