title: [Radiological aspects of rectal and colonic localizations of malignant non-Hodgkin's lymphoma. Apropos of 30 cases].
abstract: The authors review radiological and endoscopical data of 30 patients with primary or secondary colonic and rectal non Hodgkin's lymphomatous involvement, and describe the radiologic pattern of this peculiar entity. Confirmation of the diagnosis is based in all cases on the pathological study of surgical specimens or per endoscopical biopsy. Eight patients (26%) presented non specific involvement secondary to small bowel or gastric localisation. The other patients (74%) had intrinsic lesions who may either remain localised (commonly endo-enteric type) or extend to whole of the colon (infiltrating type). After a description of the radiological features of these wide spectrum lesions, the authors consider the differential diagnosis and the respective contribution of colonic endoscopy and barium enema.
