Cavernous hemangioma of the liver (cavernous hemangioma) is most commonly seen in adults and is mostly solitary and slow growing. Smaller tumors may be asymptomatic and do not require treatment. Larger tumors may manifest as hepatomegaly, which may compress adjacent organs and cause abdominal pain and distention. The most dangerous complication of hepatic cavernous hemangioma is acute hemorrhage. (i) Clinical examination. An abdominal mass associated with the liver may be found, with varying mass texture and no abnormal liver function manifestations. (ii) B-mode ultrasound. A strongly echogenic lesion with clear margins and homogeneity may be seen. For hemangiomas larger than 3-4 cm, a hypoechoic gap consistent with dilated vascular sinuses or blood pools may be seen within the lesion. (iii) CT scan. A typical cavernous hemangioma is a hypodense mass, and a delayed scan with contrast injection becomes an enhanced image compared to the surrounding liver tissue. (iv) Hepatic arteriogram and nuclear hepatic blood pool scan. The diagnostic value of hepatic cavernous hemangioma is greater, especially for the differential diagnosis with hepatocellular carcinoma. On hepatic blood pool scan images, the lesion area of hepatocellular carcinoma appears as a radiolucent area, while the lesion area of hemangioma is the opposite. The effective treatment for hepatic cavernous hemangioma is hepatectomy. Depending on the extent of the lesion, an appropriate amount (lobar or partial) of the liver is removed. Hepatic artery ligation or hepatic artery embolization can be performed for lesions that invade large portions of the liver tissue and cannot be resected, followed by radiation therapy to achieve palliative results.
