HEPATIC CALCIFICATION - 09/09/11
Résumé |
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.7 Axial imaging techniques, such as ultrasound and CT scan, have significantly improved our ability to evaluate hepatic calcifications, not only by confirming their intrahepatic location, but also by providing valuable morphologic information about any associated lesion. In addition, the greater contrast resolution of CT scan has increased the sensitivity for detection of calcification compared with plain radiograph.21 Causes of hepatic calcifications are as follows:
• | Infections

• | Vascular

• | Benign tumor

• | Primary malignant tumor

• | Metastatic tumor

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.15
