The patient was a 33-year-old female. She was pointed out as showing an abnormal shadow in the left upper pulmonary field in a chest roentgenogram on annual screening. Chest CT showed a cystic lesion in the left lung upper lobe suspected to be a bronchogenic cyst. She was followed-up because she presented with no symptoms. She visited a hospital because of fever, back pain, and bloody sputum 5 years before the surgery. She was diagnosed with bronchial cystic infection and pneumonia, and was treated with an antimicrobial agent. However after that, cystic infection and relatively severe pneumonia requiring hospitalization repeated 4 times in 3 years. She was referred to our hospital for further examination and treatment. Chest CT revealed a cystic mass in the left lung upper lobe. Chest CT also suggested adhesion to the left subclavian artery, aortic arch, and main pulmonary artery. Then, we performed left upper division segmentectomy using indocyanine green to determine the intersegmental plane via anterolateral thoracotomy. The postoperative diagnosis was a bronchogenic cyst. Here, we report a patient with a left lung upper lobe bronchogenic cyst treated by left upper division segmentectomy.
