title: [A case of primary pulmonary MALT lymphoma as a nodular shadow on CT scan, and relapsed with diffuse micronodular shadows after surgical resection at 7 years ago].
abstract: A 76-year-old man without symptoms was admitted to our hospital for investigation of an abnormal chest shadow in 1994. His chest radiograph showed a nodular shadow in the lingual lobe. Segmentectomy was performed and the histological diagnosis was MALT (mucosa-associated lymphoid tissue) lymphoma. In June 2001, there were no abnormal shadows on the chest radiograph or in 10 mm slice CT. However, high-resolution CT with 2-mm slice thickness revealed diffuse micronodular shadows in both lungs. A relapse of MALT lymphoma was diagnosed by immunohistochemical analysis of tissue specimens obtained by transbronchial lung biopsy. It was observed that the patterns of radiological findings in primary pulmonary MALT lymphoma cases may differ between the initial state and a relapse.
