Imaging manifestations of pulmonary mucosa-associated lymphoid tissue lymphoma / 实用放射学杂志

ABSTRACT

Objective To investigate the imaging characteristics of pulmonary mucosa-associated lymphoid tissue(MALT)lym-phoma,in order to improve the diagnosis of this disease.Methods X-ray and CT features of 1 9 cases of pulmonary MALT lympho-ma confirmed by operation or biopsy were retrospectively analyzed.Results Among 1 9 cases,there were 4 cases with a single nod-ule,2 cases with a single consolidation,5 cases with multiple consolidations,2 cases with a single patchy shadow,4 cases with patchy consolidations,1 case with multiple patchy shadows combined with irregular cavities,and 1 case with diffused interstitial changes.Grossus air bronchogram was found in 1 1 cases with nodules,consolidations and patchs.Irregular margin was found in 1 5 cases.Spiculation was found in 3 cases.Pleural retraction was found in 2 cases.Pleural effusion was found in 3 cases.Conclusion Pulmonary MALT lymphoma can be showed as solitary nodule,patchy shadow,consolidation,cavity and diffused interstitial change.Pulmonary MALT lymphoma should be considered if such lesions combined with grossus air bronchogram,irregular mar-gin,spiculation or plural retraction..
