[Radiodiagnosis of gastrointestinal lymphomas].

Radiological synopsis of primary gastrointestinal lymphoma depends on the growth direction and dynamism of the tumor, i.e. grade of malignancy and stage of the pathological processes at diagnosis. Initial nodal-polypoid lesions, because of their mucosal/submucosal aggregation, in combination with more or less pathological small bowel relief, are successfully diagnosed by conventional barium studies. Progressive ulcerous and narrowing destruction of the gut wall, as a result of the advanced mural infiltration, increases the success rate of tomographic examination. Tomographic imaging, particularly computed tomography, is considered the primary method, alongside the selective small bowel double-contrast study for demonstration of diffuse tumor infiltration.
