Abstract
Hepatic hemangiomas (HHs) are the most common type of benign liver tumor, with an incidence of ~3–20 % [1]. Among the different pathological types of HH, cavernous hemangioma is most commonly seen in clinics, and tumors are often discovered by ultrasound or contrast-enhanced CT in physical examinations. The majority of HH patients have no clinical symptoms, but some suffer from upper abdominal pain and discomfort. Although surgical resection is often adopted for the treatment of HHs, there are still no uniform standards in terms of surgical indications. Other treatment methods include radiofrequency ablation, hepatic artery embolization, suture and ligation, hepatic artery ligation, and microwave coagulation. For a small number of patients with diffuse HHs or unresectable giant HHs, liver transplantation can be performed if liver decompensation occurs.
