[Primary malignant lymphoma of the stomach. Barium meal, sonography and computed tomography].

The features of barium meal, ultrasonography and CT in 18 patients with proven primary gastric lymphoma were analyzed retrospectively. Only barium meal could reveal highly suspicious features in 16 cases, whereas ultrasonography and CT showed a non specific wall thickening. Although single signs in a barium meal are non-specific, the combination of clubbing of mucosal folds, atypical ulcerations and extensive mural infiltration is highly suspicious of lymphomatous involvement. A negative barium meal, ultrasonography and/or CT result does not exclude gastric lymphoma.
