Imaging findings
Chest radiograph shows multiple well-defined lung masses. CT reveals very well-defined, consolidated masses with sharp margins, some peripheral ground glass, and patent air bronchograms, indicating a bronchial distribution. These findings are highly characteristic of pulmonary lymphoma.
Key takeaways
Primary pulmonary lymphoma, particularly MALToma, can present as asymptomatic, well-defined consolidated lung masses with air bronchograms and sharp margins, often with a bronchial distribution. This distinct appearance is a strong indicator for lymphoma in the differential for chronic consolidation, even when initial biopsies are inconclusive. These are often low-grade and may show stability over months.
