Abstract
The pulmonary marginal zone B-cell lymphoma of bronchus associated lymphoid tissue of the lung (BALT) is a rare illness that can remain without symptoms. Radiological findings of pulmonary lymphoma are heterogeneous. In literature, bronchiectasis is only described in one patient who also had besides adenomegalies. We reported on a 48-year-old female patient. She showed symptoms consistent with dyspnea with productive cough; there were crepitant sounds in the auscultation. Pulmonary functional test has shown a severe restrictive pattern with a low FVC and DLCO. CT scan showed bronchiectasis in the medium lobule without adenomegalies. Echocardiogram was normal, and the laboratory findings only showed leukocytosis. There were no findings in the bronchoscopy, but the lung biopsy showed a B-cell pulmonary lymphoma (positive to CD20 and CD79a in immunostaining). A wide variety of radiological manifestations has been previously described; however, we have presented this rare case, with bronchiectasis, as unique radiological finding.
