A 59-year-old man came to our hospital for further examination of multiple small nodular lesions in both lungs. Chest CT scan revealed multiple nodular lesions in rt-S6, It-S5, and It-S9 (two lesions). All of these nodules measured about 10 mm or less and those in It-S9 had spicula. Bronchoscopic examination did not yield a definitive diagnosis, so open lung biopsy was done. The open lung biopsy specimen revealed intra-pulmonary lymph nodes with anthracosis and pulmonary emphysema. Intrapulmonary lymph nodes are very difficult to distinguish from small lung tumors by radiographic examination alone, so the possibility that small nodules in the lungs may be intra-pulmonary lymph nodes should be kept in mind.
