Pulmonary manifestations of lymphoma: A pictorial essay

Lymphomatous involvement of the lungs manifests in an infinite number of ways. Often there is a considerable overlap of the patterns of manifestations which comes as a diagnostic challenge to the radiologist. We retrospectively reviewed the pulmonary manifestations of biopsy proven cases of primary or secondary non-Hodgkin's lymphoma or Hodgkin's lymphoma. The patterns of lung involvement were then classified into broad categories which included large masses, mass like consolidation, nodules with or without cavitation, ground glass and lymphangitis/ perilymphatic pattern. This article illustrates the spectrum of CT manifestations of lung involvement in non-Hodgkin's lymphoma as well as Hodgkin's lymphoma.
