We reported a 72-year-old woman who had a massive hemoptysis due to traction bronchiectasis in the left upper lobe. The patient underwent left radical mastectomy followed by thoracic radiotherapy for left breast cancer. The chest computed tomography showed traction bronchiectasis in the atrophic left upper lobe and the bronchial angiography showed hypervascularization of bronchial and internal thoracic arteries to the left upper lobe. Left upper lobectomy was performed after bronchial embolization for recurrent massive hemoptysis. Postoperative course was uneventful. Pathologic findings showed non-anatomical but clearly-bordered traction bronchiectasis with hypervascularized bronchial artery in the left upper lobe. These lesions were consistent with the field of the previous radiotherapy. Traction bronchiectasis causing massive hemoptysis should be considered as one of pulmonary sequelae after thoracic radiotherapy.
