Hepatic hemangioma 2.1cmx1.5cm is usually not serious. Hepatic hemangioma is a common primary benign tumor of the liver, which is a mass structure composed of a large number of arteriovenous vascular malformations in the liver, most of which are slow-growing and seldom show malignant tendency. Spontaneous rupture is rare and generally not serious. Hepatic hemangioma of 2.1cmx1.5cm is small in size and does not have much effect on the physiological function of the liver. If there is no obvious discomfort, it does not need treatment, and ultrasonography can be performed every 6-12 months after diagnosis in order to dynamically observe its changes. If the tumor is found to be growing rapidly and has the tendency of malignant transformation, early surgical resection is recommended. Patients with hepatic hemangioma should maintain a regular routine, avoid overwork, avoid eating excessive greasy food, have regular checkups, and seek medical advice if there are obvious discomfort symptoms.
