Hyperechoicity in the right lobe of the liver is the result of an ultrasound of the liver. This condition may be a calcified focus in the right lobe of the liver or an intrahepatic bile duct stone, and possibly an intrahepatic hemangioma. Echo enhancement relative to intrahepatic hemangiomas, calcified foci, and stones may also be strongly echogenic. Intrahepatic calcified foci may be caused by abnormal calcium and phosphorus metabolism, trauma, inflammation, and may be associated with parasitic infections or even neoplastic lesions. However, most intrahepatic calcified foci are isolated lesions. The causes of intrahepatic bile duct stone formation are very complex and are related to a variety of factors, including biliary tract infections, biliary parasites, cholestasis, anatomic variations of the bile ducts, and malnutrition. Most intrahepatic bile duct stones are brown bile pigment stones containing bacteria. The development of intrahepatic hemangiomas may be closely related to congenital malformations of the terminal blood vessels of the liver, hormonal abnormalities in the body, or dilatation of capillary tissue following infection.
