CTICasesPulmonary marginal zone B-cell lymphoma of MALT
Imaging findings
Chest CT shows striking, bilateral, smooth interlobular septal thickening, peribronchovascular cuffing, and a left basal consolidative mass. Transbronchial biopsy confirmed marginal zone B-cell lymphoma of MALT with plasmacytoid differentiation.
Key takeaways
Primary pulmonary B-cell lymphoma of MALT can atypically present with a lymphatic distribution, manifesting on CT as smooth interlobular septal thickening and peribronchial cuffing, mimicking pulmonary edema or lymphangitic carcinomatosis.
