OBJECTIVE: To investigate the clinical and computed tomography (CT) appearances of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma.
METHODS: The CT findings and clinical data of 13 patients with pathologically proven pulmonary MALT lymphoma were retrospectively reviewed.
RESULTS: Among these 13 patients, seven presented no notable abnormalities, six manifested respiratory symptoms including cough, expectoration, and dyspnea; one of these six patients experienced fever. Chest CT showed solitary nodule in 2 patients and multiple nodules in 3 patients; meanwhile, it showed solitary consolidation in 3 patients and multiple consolidations in 5 patients. Other CT findings included air bronchogram (n = 13), airway dilatation (n = 4), ground glass opacities (n = 5), and interstitial changes (n = 5). One patient had mediastinal lymphoadenopathy and 2 had pleural effusion. Pathology showed massive lymphocyte infiltration; cells with notable nuclear atypia were also seen, which were generated from B cells.
CONCLUSIONS: The main CT findings of pulmonary MALT lymphoma include nodules, mass or patchy consolidations with air brochogram; hilar and mediastinal lymphadenopathies are rare. Clinical diagnosis should also be based on pathological findings and immunohistochemical results.
