A 58-year-old man was found to have an abnormal shadow on chest computed tomography (CT). The size and density of the nodule increased gradually over 7 years. Partial lung resection was performed by a thoracoscopic procedure. The pathological examination and gene analysis revealed that the tumor was primary pulmonary B-cell lymphoma of mucosa associated lymphoid tissue (MALT lymphoma). The CT findings showed that the level of substantial shadow with air bronchograms gradually increased in the center of the mass shadow, while a radial filamentous and ground glass shadow increased in the periphery. The pathological findings showed a cellular lymphocytic infiltrate that had expanded without destroying the existing blood vessels and bronchi in the center area of the tumor, while had expanded in the interstitial area along with vessel bundles in the border area. The CT findings were consistent with the pathological findings.
一名58岁男性在胸部计算机断层扫描（CT）中发现异常阴影。结节的大小和密度在7年中逐渐增加。通过胸腔镜手术进行了部分肺切除术。病理检查和基因分析显示，该肿瘤为黏膜相关淋巴组织原发性肺B细胞淋巴瘤（MALT淋巴瘤）。CT表现显示，肿块阴影中心有空气支气管征的实性阴影水平逐渐增加，而周边有放射状条索状和磨玻璃阴影增加。病理表现显示肿瘤中心区域有细胞性淋巴细胞浸润，未破坏现有血管和支气管，而在边缘区域沿血管束在间质区域浸润。CT表现与病理表现一致。
