[An intra-pulmonary lymphnode resembling typical pulmonary primary adenocarcinoma on high-resolution computed tomographic (HR-CT) chest images].
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.
