[Contribution of imaging in malignant non-Hodgkin lymphomas of the small intestine. Apropos of 32 cases]. / Apport de l'imagerie dans les lymphomes malins non hodgkiniens du grêle. A propos de 32 cas.

The authors report a retrospective study concerning 32 cases of non Hodgkin lymphoma of the small intestine, histologically confirmed. All patients underwent digestive opacification. Ultrasonography was performed in 15 cases and CT scan was performed in 6 cases. The average age was 36 years and the sex-ratio was 3.4. The classical radiological signs described in the literature were found in our patients. The diagnosis of lymphoma was easily suggested in the presence of polymorphic and multifocal lesions, and especially the aneurysmal appearance. Abdominal sonography and computed tomography contributed to the diagnosis and also helped to relate an abdominal mass to its digestive origin, by showing a classical "sandwich" appearance.
