Most hepatic hemangiomas do not usually have any uncomfortable symptoms and are mostly detected during physical examinations or imaging examinations for other diseases. After the liver hemangioma is found, the patient’s most troubled and concerned question is, is liver hemangioma a malignant tumor? Let me tell you first: hemangioma of liver is benign tumor of liver, not cancerous! It is just a fox like a plum to scare people. The specific causes of hemangioma of the liver are mainly related to congenital developmental factors, which are found in some patients after years of hormone application. Hemangiomas are essentially vascular malformations in the liver with dilated blood vessels in the form of sponges or honeycombs, the vast majority of which are spongiform hemangiomas that vary in diameter from large to small. They can be divided into small hemangiomas (<5cm in diameter), medium hemangiomas (5-10cm in diameter), large hemangiomas (10-15cm), and giant hemangiomas (>15cm in diameter) according to their diameter. Smaller hemangiomas of the liver do not cause any discomfort in humans. Large hemangiomas can cause nausea, abdominal pain and distention, loss of appetite and other pressure symptoms. Very few hemangiomas that grow on the edge of the liver or are too large can rupture spontaneously or as a result of trauma, causing hemorrhage. Patients should not panic, as only a very small number of hemangiomas rupture, and moderate to low hemangiomas in the central part of the liver are particularly unlikely to rupture. Do hemangiomas in the liver need to be treated? How is it treated? Do they require surgery? The current consensus is that small hemangiomas located in the central part of the liver generally do not need treatment, but annual ultrasound or CT follow-up should be done; those with a diameter of >5cm, especially those growing at the edge of the liver and prone to rupture, and those with a significant growth trend (accelerated growth rate), and when the tumor increases to a certain extent, abdominal pain and bloating symptoms should be treated actively. In the past, surgical resection was mostly used, but because of the high trauma, bleeding and risk of surgery, it has been replaced by new interventional techniques in recent years. The principle of treatment for hepatic hemangioma is changing from traditional surgical treatment to minimally invasive treatment modalities such as radiofrequency ablation of the tumor and vascular intervention. The principle of radiofrequency ablation is to shrink or completely disappear the tumor by causing necrosis of the tumor tissue through radiofrequency ablation, forming a blood clot and then fibrosis of the tumor. Vascular interventions involve the use of embolic agents (e.g. gelatin sponges) to fill the tumor and embolization of the main blood vessels supplying the tumor, also resulting in the formation of a blood clot in the tumor cavity and subsequent fibrosis. Only in the case of large hemangiomas is surgical excision a highly invasive treatment used.
