[Contribution of computed tomography in the staging of abdominal malignant lymphomas (author's transl)]

The authors present their experience of Computed Tomography in the staging of abdominal sub-diaphragmatic extension in 144 cases of malignant lymphoma of the lymph nodes (76 cases of Hodgkin's disease and 68 non-Hodgkin lymphomas). The method provides accurate information on sub-mesocolic lymph node involvement, particularly when hypertrophy is pronounced. It may also be used to assess supra-mesocolic extension of the disease, which is inaccessible to lymphography, and to study the size and, mainly, the structure of the liver and spleen tissues. Easy to perform reliable and non-invasive, the scanner constitutes a new and important means of assessing the extension, course and response to treatment of malignant lymphomas.
