The more common type is cavernous hemangioma. Hepatic cavernous hemangiomas are common in middle-aged patients and are mostly solitary or multiple; the incidence is approximately equal in the left and right liver. The tumor grows slowly and has a course of several years. When the tumor is small, it is asymptomatic. After enlargement, it mainly manifests as enlargement of liver or compression of adjacent organs such as stomach and duodenum, causing symptoms such as epigastric discomfort, abdominal distension, belching and abdominal pain. Diagnosis: Clinical manifestations, ultrasound, hepatic arteriography, CT, MRI or radionuclide scan and other examinations are not difficult to diagnose. Surgical resection is the most effective method to treat hepatic cavernous hemangioma. However, small, asymptomatic hepatic cavernous hemangioma does not need treatment and can be examined by ultrasound at intervals of 3-6 months to dynamically observe changes in the period. If the tumor is 8 cm in diameter or symptomatic, then hepatic partial resection or lobectomy of the liver for extraperitoneal tumor can be performed depending on the extent of the lesion. For those with a diameter of less than 15 cm, hemangioma bundling can also be used. For those with extensive lesions that cannot be removed, hepatic artery ligation with embolization is feasible. The largest surgically resected hepatic cavernous hemangioma in China was 63 cm × 48.5 cm × 40 cm, weighing 18 kg. The most dangerous complication of hepatic cavernous hemangioma is acute abdominal hemorrhage caused by tumor rupture, which can often lead to death.
