Table 3. Summary of the computed tomography features in the malignant spectrum of pulmonary lymphoproliferative disorders
Lymphoproliferative lung disordersComputed tomography features
MALT lymphomaNodules or consolidation
Multiple/bilateral (70%)
Hilar/mediastinal nodes (30%)
Ground-glass attenuation (halo sign)
Rarely cysts, pleural effusion, tree-in-bud
High-grade primary large pulmonary B-cell lymphomasNodule or mass cavitation in 50% Rarely pleural effusion
Lymphomatoid granulomatosisBilateral nodules/masses
Coalescence and/or cavitate
Pleural effusion (30%)
Hilar adenopathies (<25%)
Uncommon: single nodules, alveolar opacities and reticulonodular diffuse lesions
Follicular lymphomaGround-glass opacities (crazy paving)
Intravascular large B-cell lymphomaBilateral reticular shadows
Reticulonodular or nodular shadows
Ground-glass opacities
Wedge-shaped subpleural opacities
Pleural effusion
Nasal-type T-/NK-lymphomasNodules or excavated masses
Pleural effusion
Anaplastic large cell lymphoma, T-cell typeMasses or single nodules
Mycosis fungoidesNodules with halo signs
Peripheral consolidation
Crazy paving pattern
Primary pulmonary Hodgkin diseaseSolitary mass or multinodular disease
Air bronchograms or cavitation
Pleural effusion, lymphadenopathy
  • MALT: mucosa-associated lymphoid tissue; NK: natural killer cell.
