Pitfalls to avoid: the right paraspinal pseudotumor.
Fat in the fissure for the ligamentum teres, if abundant and sagittally oriented, will outline the right margin of the lateral segment of the left lobe of liver. This produces the appearance of a right paraspinal mass on plain abdominal radiographs. The nature of the anatomical relationships has been demonstrated using computed tomography.
