The identification of calcification in the right upper quadrant is a common plain film finding, but for it to be of hepatic parenchymal origin is relatively rare. It is more likely to arise from structures projected in front of or behind the liver, such as extrahepatic biliary tree, kidney, adrenal, pleura, and costal cartilage.<sup>7 Darlak J.J., Moskowitz M., Katten K.R.

In addition, the greater contrast resolution of CT scan has increased the sensitivity for detection of calcification compared with plain radiograph.<sup>21 Scatarige J.C., Fishman E.K., Saksouk F.A. , e al.

Although a wide variety of causes of hepatic calcification have been described, worldwide the most common causes are calcified granulomas and hydatid cyst, followed by calcification associated with hepatic neoplasms.<sup>15 Reeder M.M.
