NON-HODGKIN LYMPHOMA OF THE LUNGS

Twenty-seven consecutive cases of pulmonary involvement by non-Hodgkin lymphoma, including 2 cases of primary pulmonary disease, were analyzed. The radiological manifestations of illness were divided into (a) nodular (subpleural, deep parenchymal, or perihilar), (b) pneumonic-alveolar (segmental or lobar), (c) bronchovascular-lymphangitic (central bronchovascular or diffuse lymphangitic), and (d) miliary-hematogenous. Histiocytic lymphoma was associated with infiltration of rapid onset in 6, cavitating nodules in 2, and diffuse lymphangitic dissemination in 9. Of 16 patients with lymphocytic lymphoma, 7 had lobar or segmental alveolar involvement.
