A 60-year-old woman with a lung tumor was admitted to our hospital for surgical treatment. Chest computed tomography (CT) showed a 23×21×20 mm nodule in the right lower lobe. Although the lung nodule was thought to be benign due to CT image findings, its size was apparently larger than that of CT image at four years ago. So, we decided to resect the nodule and performed a partial lung resection under video-assisted thoracic surgery. The tumor was histopathologically diagnosed as a paraganglioma and scored 0 point in pheochromocytoma of the adrenal gland score( PASS). Since no abnormal uptake that indicates primary site was not found on fluorodeoxyglucose-positron emission tomography (FDGPET) performed after surgery, we diagnosed this tumor as a primary pulmonary paraganglioma. She is still alive without recurrence.
