The radiographic manifestations of pseudolymphoma of the stomach.
Pseudolymphoma of the stomach is a benign proliferation of lymphoid tissue which can be mistaken histologically for malignant lymphoma. The etiology is unknown but in most cases it is believed to be a reaction to chronic peptic ulcer disease. The clinical records and radiographs of 18 patients with pseudolymphoma of the stomach were reviewed. The radiographic findings fell into 3 relatively distinct groups: tumor masses, enlarged gastric rugae, and well-defined benign-appearing ulcers. All but 2 cases demonstrated ulcers radiographically and all cases had ulcers or erosions on pathological examination.
