The radiology corner: the small bowel in immunoglobulin deficiency syndromes.
Recent advances in immunology have permitted recognition of a group of patients who have gastrointestinal manifestations as part of an immunoglobulin deficency syndrome. Such immunoglobulin deficiency may be primary or may be secondary to a variety of diseases. We have classified and described the small bowel roentgen features associated with the various immunoglobulin deficiency syndromes as follows: 1. the sprue pattern, as seen in hypogammaglobulinemic sprue and in Ig-A deficient sprue; 2. multiple nodular defects; 3. inflammatory changes secondary to giardiasis, associated with immune deficiency diseases; 4. thickening of the small intestinal folds, as seen in the plasma cell dyscrasias, lymphoma, intestinal lymphangiectasia and amyloidosis.
