Hemangioma: 

• A hemangioma is a benign, congenital tumor consisting of large, blood-filled cystic spaces. Cavernous hemangioma is the most common benign tumor of the liver. The tumor is found more frequently in females. Patients are usually asymptomatic; although a small percentage may bleed, causing right upper quadrant pain. 
• Hemangiomas enlarge slowly and undergo degeneration, fibrosis, and calcification. They are found in the subcapsular hepatic parenchyma or in the posterior right lobe more than the left lobe of the liver.
