Lymphography in patients with suspected malignancy or fever of unexplained origin

Forty-four patients underwent bipedal lymphography for evaluation of fever of unexplained origin, or because a malignant tumor (usually lymphoma) was suspected clinically. Extensive prior medical evaluation was inconclusive. The lymphograms were of no apparent value in detecting the etiology of the illness. Reactive follicular hyperplasia was frequently seen and sometimes simulated lymphoma on the lymphogram. The primary value of lymphography in such cases is as an aid in planning biopsy and surgery.
