Tumor carcinoide e sequestro pulmonar

pulmonary sequestration is defined as a mass of lung tissue separated from the tracheobronchial tree and irrigated by an anomalous systemic artery. it is rarely seen in conjunction with lung neoplasms. we report the case of a 39-year-old female patient diagnosed with a carcinoid tumor, located in the intermediate bronchus and accompanied by bronchiectasis in the right lower lobe. the patient underwent thoracotomy for the resection of the affected area. during surgery, she presented with significant hemorrhage resulting from the transection of the anomalous artery that irrigated an intralobar pulmonary sequestration, which was located in right lower lobe and had not been identified in pre-operative examinations.
