The patient was admitted due to “a mediastinal mass found during health check-up four months ago”. Four months ago, she was admitted in a local hospital due to gas poisoning, during which CT showed a right posterior mediastinal mass. Later she was then discharged after the gas poisoning was resolved. She then visited our hospital for surgical treatment. She has a previous history of hypertension for 20 years and diabetes for 7 years. She underwent resection of uterine myoma 10 years ago.
