Introduction: Pulmonary sequestrum is a rare congenital lung anomaly defined as an area of dysplasia and nonfunctional lung tissue with abnormal systemic blood supply and various forms of venous drainage. We report the case of a 43-year-old man who was followed up for prostate adenocarcinoma with bone and lung metastases. The diagnosis of bronchopulmonary sequestration was made. Case report: The patient was 62 years old and was being followed for metastatic prostate adenocarcinoma to the bone. The frontal chest radiograph showed a poorly limited right basal opacity. Bronchial endoscopy noted an inflammatory appearance of the right lower lobar bronchus. A thoraco-abdomino-pelvic CT scan was requested as part of the extension work-up to identify a focus of intra-parenchymal condensation on the right posterior basal side vascularized by an abnormal systemic vessel emanating from the descending thoracic aorta in favor of an intra-lobar sequestration. Discussion and Conclusion: Pulmonary sequestration is a rare malformation whose diagnosis must be evoked in front of repeated infections in the same pulmonary territory, in particular the posterobasal territory. Multislice CT or MRI angiography are the examinations of choice for diagnosis and assessment. Surgical treatment remains the most important option.
