A Rare Radiological Presentation of Pulmonary Mucosa-Associated Lymphoid Tissue Lymphoma as Bronchovascular Thickening and Ground Glass Opacities with Concurrent Pancreas Involvement

Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease and usually presents as pulmonary masses, mass-like consolidation, or pulmonary nodules on chest images. We report a case of a 43-year-old man with symptoms of chronic cough for 1 year, showing bilateral diffuse bronchovascular bundle thickening and focal ground glass opacities on a chest computed tomography scan. Video-assisted thoracoscopic surgery was performed and the final pathologic diagnosis was pulmonary MALT lymphoma. Concurrent involvement of the pancreas was discovered during staging workup. After diagnosis, he was treated with cytotoxic chemotherapy and rituximab and showed improvements in his lung lesion and pancreas.
