[Case of multiple intrapulmonary lymph nodes].
A 45-year-old man who had hypertension, hyperthyroidism, and bronchial asthma was admitted to our hospital because of a low-grade fever and chest pain. The physical findings and laboratory data were almost all within normal limits except for evidence of mild inflammation and liver dysfunction. The chest X-ray findings seemed normal, but a computed tomography (CT) scan showed multiple nodules in both lower lung fields. We suspected the cryptococcosis or lung cancer. Biopsy by video-assisted thoracoscopic surgery (VATS) yielded a diagnosis of multiple intrapulmonary lymph nodes. In cases with the above radiologic findings, careful attention should be paid to making the differential diagnosis between intrapulmonary lymph nodes and primary lung cancer. The promotion of diagnostic imaging and advances in techniques have made it easier to identify small peripheral nodules in the lungs, and we now know of their existence. Solitary intrapulmonary lymph nodes are encountered frequently, but multiple or increasing numbers of nodes, as in our case, are very rare. Moreover, because cases with elevated CEA levels have been reported, differentiation from lung cancer appears to be important.
