Right upper quadrant calcification: Porcelain gallbladder disease

Large solitary calcification in the right upper quadrant is rarely seen in the United States. It may indicate disease in the gallbladder, adrenal glands, kidneys, pancreas, lungs or chest wall. Disease processes associated with calcification in these organs include echinococcal cysts, calcified renal cysts, chest wall masses and degenerative cystic lesions of the pancreas and adrenal glands. However, if calcification is associated with porcelain gallbladder, the incidence of carcinoma is high. Treatment consists of cholecystectomy with a careful search for malignancy.
