Pseudotumor due to pulmonary infarction diagnosed by video-assisted thoracoscopic surgery.
We report a case of pulmonary infarction in a 50-year-old man who was referred for an asymptomatic coin lesion in the periphery of the right lower lobe. Computed tomography of the chest demonstrated a subpleural solitary nodule with spicular radiation. Video-assisted thoracoscopic surgery was performed to obtain a histological diagnosis. Thoracoscopic examination showed that the tumor was dark purple and the central portion was gray, indicating blood retention in the lung and necrotic and fibrotic tissue in the central portion. This is the first case of pseudotumor due to pulmonary infarction that was diagnosed by video-assisted thoracoscopic resection.
