Approach to the differential diagnosis of abdominal calcification:
- AXR AP is where an abdominal calcification is most commonly encountered incidentally
- AXR lateral may be of use to better determine the location of the calcification
- US is the next step to help in definitively determining the location of the calcification and determining if there are any side effects caused by it such as cholecystitis, appendicitis, pyelonephritis, torsion, mass effect or vascular occlusion
- CT and MR are useful in working up calcified abdominal masses that are suspicious for malignancy
