Lymphoid tissue is a normal component of the lung. The various lymphoproliferative diseases affect the lung parenchyma. The purpose of this article is to classify various lymphoproliferative diseases and to understand their computed tomography features of pulmonary involvement. The examples include follicular bronchiolitis, lymphocytic interstitial pneumonia, plasma cell granuloma, Castleman disease, lymphomatoid granulomatosis, and mucosa-associated lymphoid tissue lymphoma. Pathologic correlation is helpful for understanding imaging findings and their pathophysiology.
