The mediastinum in Hodgkin's and non‐Hodgkin's lymphomas

The mediastinum is commonly involved with disase in patients with Hodgkin's and non-Hodgkin's lymphomas. The involvement may be permeative, or individual groups of nodes may be enlarged. The parietal nodes of the mediastinum may also be abnomal with either type. Precise mapping of all disease is important when radiation therapy is to be a major component of treatment planning. Detection of relapse following mantle irradiation is frequently dependent on having a new comparative baseline after the distortions of mediastinal contours consequent to radiation treatment have stabilized.
