RADIOLOGICAL APPEARANCES OF LYMPHOMAS ARISING FROM MUCOSA-ASSOCIATED LYMPHOID-TISSUE (MALT) IN THE LUNG

We review the radiological findings in 13 patients with histologically proven (n = 10) or clinically diagnosed (n = 3) lymphomas arising in mucosa-associated lymphoid tissue (MALT) of the lung. These rare B-cel l lymphomas typically follow an indolent course, and many cases are st ill being incorrectly described in current radiological literature und er the term pseudolymphoma, The patients frequently give a history of autoimmune disease involving the affected organ, and involvement of an other mucosal site as part of a disseminated MALT lymphoma, is common, The radiographic patterns of pulmonary parenchymal involvement in lun g MALT lymphomas have been reviewed, and correlation made with their c linical behaviour.
