The disappearance of splenic hemangioma after one year may be the natural regression of hemangioma. Hemangioma is a vasculogenic tumor with abnormal proliferation of vascular endothelial cells, which is a common benign tumor that can occur in many parts of the body, and is generally divided into the types of capillary hemangioma, cavernous hemangioma, and venous hemangioma. Hemangiomas generally have no periosteum and are poorly demarcated. In the skin or mucous membrane, they may appear as raised bright red lumps, or dark red or purplish red spots. In the internal organs, they are often nodular. It is more common in children, can be congenital, and grows with the development of the body, and usually stops developing in adulthood, and can even subside naturally. If the visceral hemangioma is large and cannot subside naturally, it can be treated with oral propranolol or glucocorticoids, local injection, embolization or surgery under the guidance of professional doctors.
