Radiological manifestations of primary pulmonary MALT lymphoma. a An oval mass-like consolidation with surrounding ground-glass opacities in the anterior segment of the left upper lobe with favorable contrast enhancement. b Multiple poorly marginated nodules with air bronchograms and nodules distributed along with the bronchovascular bundle. c Multifocal patchy ground-glass opacities and consolidations in both lungs, increased number of ill-defined nodules in bilateral lower lobes, combined with underlying bronchiectasis with diffuse centrilobular ill-defined nodules in both lungs with lower lobe predominance. d Irregular mass-like consolidation in the superior segment of the right lower lobe with obliteration of the superior segmental bronchus with small right pleural effusion and bronchiectasis in underlying pulmonary emphysema, combined with diffuse bronchial wall thickening.
