[The value of computer tomography in the staging of primary lymph node neoplasms (author's transl)].

Staging was undertaken in 118 patients with primary lymph node neoplasms; the sensitivity of computer tomography in the paraaortic region was 80%, that of lymphography 89%. Specificity of computer tomography was 93%, of lymphography 95%. In the iliac region, sensitivity was 81% (CT) and 90% (lymphography), and specificity was 90% (CT) and 97% (Lymphography). The value of computer tomography should, however, be stressed, since it can demonstrate lymph nodes not shown by lymphography, including those in the mediastinum, as well as lesions in the spleen, liver and lungs.
