In intralobar pulmonary sequestration, this tissue is located within the visceral pleura of a pulmonary lobe, and its venous drainage is into the pulmonary veins. In the same period, the vascular supply, originating from branches of the splenic vascular plexus, accompanies the bronchial generations.(1) Congenital pulmonary anomalies are rare, the most common being lobar emphysema, cysts in the lungs, cystic adenomatoid malformation and pulmonary sequestration.(2) Bronchopulmonary sequestration is characterized by an area of abnormal, nonfunctional pulmonary tissue, which receives its blood supply via a systemic artery and has no connection with the tracheobronchial tree. The buds elongate, developing all of the lung segmentation by the 36th day. The ventral wall of the pharynx of the fetus migrates caudally, forming the larynx and the trachea, as well as the right and left lung buds. The development of the tracheobronchial tree begins on the 24th day of embryogenesis. Hemoptise Sequestro broncopulmonar Tomografia computadorizada espiral. Apresentou boa evolução pós-operatória e recebeu alta com acompanhamento ambulatorial. O paciente foi submetido à cirurgia para a retirada do tecido anômalo, que foi realizada com sucesso. Após a realização de TC com contraste endovenoso, foi evidenciada a presença de sequestro pulmonar. Neste relato, descrevemos o caso de um paciente de 56 anos com hemoptise e imagem hipotransparente retrocardíaca em base de hemitórax esquerdo na radiografia de tórax. Essa anomalia envolve o parênquima e a vascularização pulmonar, sendo classificado como intralobar ou extralobar. O sequestro pulmonar é uma rara anomalia congênita, caracterizada por tecido pulmonar embrionário não funcionante, perfazendo 0,15-6,40% de todas as malformações pulmonares congênitas. Hemoptysis Bronchopulmonary sequestration Tomography, spiral computed. The postoperative evolution was favorable, and the patient was discharged to outpatient treatment. The patient underwent surgery, in which the anomalous tissue was successful resected. Chest CT scans with intravenous contrast revealed pulmonary sequestration. A chest X-ray showed an area of opacity behind the cardiac silhouette in the base of the left hemithorax. We report the case of a 56-year-old male presenting with hemoptysis. This anomaly, which is classified as intralobar or extralobar, involves the lung parenchyma and its vascularization. Pulmonary sequestration accounts for 0.15-6.40% of all congenital pulmonary malformations. Pulmonary sequestration is a rare congenital anomaly, characterized by nonfunctional embryonic pulmonary tissue.
