Porcelain gallbladder is a condition
characterized by calcium salt deposits in the wall of a chronically inflamed gallbladder. The calcifications can
be thin or faintly visible, or may be amorphous, patchy, and thick. The gallbladder is generally large, but its
size can vary considerably. Most porcelain gallbladders are associated with gallstones. A plain radiograph
generally detects these, but computed tomography (CT) has a higher specificity; therefore, a CT scan
is performed to confirm the diagnosis. Due to their high risk of gallbladder carcinoma, all patients with
porcelain gallbladder should have an elective cholecystectomy.
