Lymphography for fever of unknown origin-a reappraisal

Among the lymphograms of 25 F.U.O. patients whose diagnoses were unknown after several weeks of detailed examinations, abnormalities were noted in 4. Of the 4 abnormal cases, 2 were finally diagnosed by superficial lymph nodes biopsies as having malignant lymphomas. The other 2 had no final diagnoses; though biopsies of enlarged superficial lymph nodes were performed, they showed only reactive hyperplasia. No exploratory laporatomy was performed among the 25 cases. We conclude that lymphography is not absolutely indicated in the evaluation of F.U.O.
