A 40-year-old man was admitted to our hospital for further evaluation of a pulmonary nodule in chest radiographs. The 8-mm nodular lesion was located in the right anterior basal lobe on a plain chest radiograph, and showed 1) spiculation, 2) pleural indentation and 3) a converging vessel formation in high-resolution computed tomography of the chest. The radiographic findings were highly suggestive of primary pulmonary adenocarcinoma and the patient underwent video-assisted thoracoscopic surgery (VATS) to obtain a precise diagnosis. The nodule was diagnosed histopathologically as an intrapulmonary lymph node. In cases with such radiographic findings, careful attention should be paid in the differential diagnosis to distinguish intrapulmonary lymph nodes from primary pulmonary adenocarcinoma.
一名40岁男性因胸部X线片上发现肺结节而入院进一步评估。在胸部平片上，这个8毫米的结节状病变位于右前基底段，在胸部高分辨率计算机断层扫描中显示为：1）毛刺征；2）胸膜凹陷征；3）血管集束征。影像学表现高度提示原发性肺腺癌，患者接受了电视辅助胸腔镜手术（VATS）以获得精确诊断。该结节经组织病理学诊断为肺内淋巴结。对于有此类影像学表现的病例，在鉴别诊断时应仔细注意区分肺内淋巴结与原发性肺腺癌。
