Benign Liver Tumors
Hemangiomas
Hemangiomas are usually small and asymptomatic; they occur in 1 to 5% of adults. Symptoms are more likely if they are>4 cm; symptoms include discomfort, fullness, and, less often, anorexia, nausea, early satiety, and pain secondary to bleeding or thrombosis. These tumors often have a characteristic highly vascular appearance. Hemangiomas are found incidentally during ultrasonography, CT, or MRI. CT typically shows a well-demarcated, hypodense mass; when contrast is used, there is early peripheral enhancement, followed by later centrifugal enhancement. Treatment is usually not indicated. Resection can be considered if symptoms are troublesome or if a hemangioma is rapidly enlarging. to improve heart function, interferon alfa (given subcutaneously), surgical removal, selective hepatic artery embolization, and, rarely, Liver Transplantation .
