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.
1994年，一名76岁无症状男性因胸部阴影异常入我院检查。其胸部X线片显示舌叶有一个结节状阴影。进行了肺段切除术，组织学诊断为黏膜相关淋巴组织（MALT）淋巴瘤。2001年6月，胸部X线片及10毫米层厚CT均未发现异常阴影。然而，2毫米层厚的高分辨率CT显示双肺弥漫性微小结节阴影。经支气管肺活检获取的组织标本免疫组化分析诊断为MALT淋巴瘤复发。观察发现，原发性肺MALT淋巴瘤病例的影像学表现模式在初始状态和复发时可能有所不同。
