Imaging findings
Chest radiography shows a well-defined rounded mass in the left mid-to-lower lung zone, along with a broad-based, triangular mass-like opacity abutting the left lower chest wall. Contrast-enhanced CT confirms multiple mass-like consolidations with prominent, beautiful patent air bronchograms running through them. A companion case demonstrates a solitary pulmonary nodule in the right lower lobe, lacking prominent air bronchograms but lying adjacent to a patent bronchus.
Key takeaways
Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade B-cell lymphoma that often presents as asymptomatic, slowly growing, multifocal or solitary consolidations. Classic imaging features include air bronchograms, which can also be seen in lung adenocarcinoma, organizing pneumonia, and sarcoidosis. When these findings occur in an asymptomatic patient, particularly an elderly individual, lymphoma should be strongly considered.
