title: [Radiological aspects of gastric localizations of malignant non-Hodgkin's lymphoma. Apropos of 50 cases].
abstract: The authors describe radiological features of non Hodgkin's gastric lymphomas based on a study of 50 cases, with endoscopic correlation in 43 cases. Radiographic appearance is categorized as infiltrative (40 per cent), ulcerative (26 per cent), polypoid (10 per cent) and polymorphic (24 per cent). Gastric carcinoma is the most important differential diagnosis. Since staging, therapy and prognostic are different in these two diseases, accurate radiologic diagnosis is of particular importance. Combination of several peculiar radiologic signs suggest gastric lymphoma in 56 per cent of all the cases (16 per cent for endoscopy alone); this fact demonstrate the necessity of barium meal for a more accurate diagnosis of gastric lymphomas.
