title: Gastric lymphoma, a radiologic diagnosis.
abstract: Because endoscopy and gastric cytology lack specificity, radiographic evaluation is still the most reliable means of diagnosing gastric lymphoma preoperatively. A retrospective analysis indicates that if careful attention is paid to the radiologic features, gastric lymphoma can be distinguished from gastric carcinoma in most of cases. The radiographic findings of a long segment of involvement, multiplicity of radiographic pattern, and diffuse infiltration consisting of concentric abnormal folds without significant narrowing of the lumen are characteristic of the non-Hodgkin's lymphoma.
