Abstract
A 57-year-old male patient was admitted to our center because of a cystic mass on the lower portion of the right major fissure that was found incidentally by chest X-ray. He did not have a history of trauma or anticoagulant use. The lesion was removed by video-assisted thoracoscopic surgery. Pathological examination revealed an organizing pulmonary hematoma without any complications, and a follow-up chest X-ray after 1 year showed no recurrence.
