Case Report Pulmonary sequestration: a case report and literature review

Purpose: Pulmonary sequestration (PS) is a rare congenital lung malformation. It is characterized by an abnormal mass of dysplastic lung tissue supplied by an anomalous systemic artery and separated from normal bronchopulmonary tree. Misdiagnosis and inadequate treatment can lead to recurrent pneumonia and fatal hemoptysis. Methods: We report a 45 years female was diagnosed PS, and performed a brief review about the clinical features, diagnostic strategies, and management options of the PS. Results: Her remarkable symptoms were cough and hemoptysis, the contrastenhanced computed tomography of the chest revealed a multiloculated cystic solid mass filled with low density lesions and a feeding artery from the descending abdominal aorta to the cystic solid mass was visualized, then the patient suffered a right lowerlobe resection, and the surgery and pathological examination all supported the diagnosis of intralobar sequestration. Conclusions: Symptomatic patients of the pulmonary sequestration should be treated by surgery to avoid the risk of death due to massive hemoptysis.
