CTICasesPrimary pulmonary MALT lymphoma
Imaging findings
Chest radiograph and CT scan show a mass-like area of consolidation containing air bronchograms with relatively well-defined margins in the right middle lobe, without associated lymphadenopathy or effusion.
Key takeaways
Primary pulmonary marginal zone lymphoma (MALT lymphoma) typically presents as a solitary mass-like consolidation with air bronchograms, mimicking an organizing pneumonia or localized fungal infection. The presence of well-defined margins helps differentiate it from acute infections.
