Repeat Lymphography in Non-Hodgkin's Lymphoma.

Overview

Thirty-nine patients with non-Hodgkin's lymphoma underwent repeat lymphography. The radiographic findings and effects on clinical management are discussed. The repeat examinations were technically no more difficult to perform than the initial studies. Repeat lymphograms were positive for tumor in 44% of cases. Positive findings were more frequent in patients who received no prior subdiaphragmatic irradiation or in whom the initial study demonstrated lymphomatous infiltration. Interpretative problems include reactive hyperplasia, post-irradiation lymph node alterations, and the lymph nodal distortion occasionally encountered in the treated lymph node which had been involved with tumor.
