[Primary lymphoma of the small intestine. Radiographic image of enteroclysis with double-contrast media].
The authors retrospectively reviewed the radiographic (double-contrast small-bowel enema) examinations of 20 patients with primitive small intestinal lymphomas. The diagnosis was histologically confirmed in all cases. The technique was very sensitive (100%) in detecting small-bowel abnormalities. On the contrary, a definite differential diagnosis was difficult to make (65%), except for 4 cases of lymphoma complicating celiac disease in which the presence of a nodular pattern and of thickened and irregular mucosal folds seemed to be highly specific. The most difficult differential diagnosis was with Crohn's disease. In all the cases with surgical confirmation (17), disease extent exactly corresponded to that suggested by small-bowel enema. Primitive small intestinal lymphoma is not radiologically distinguishable from secondary involvement during systemic lymphoma. From the analysis of radiological abnormalities, the authors observed that, different from previous reports, severe luminal narrowing was frequent, whereas "aneurysmal" dilatations of intestinal loops were never observed. CT was confirmed as the best technique for staging. Clinical implications of double-contrast enema in the diagnosis of primitive small intestinal lymphomas are discussed; radiographic patterns are reviewed.
