Intralobar pulmonary sequestration with aberrant feeding artery aneurysm.

ABSTRACT: Pulmonary sequestration (PS) is a rare congenital lung malformation in which nonfunctioning lung tissue is supplied by systemic arteries without normal bronchial communication. Development of aneurysms within the aberrant feeding artery is exceedingly uncommon and associated with high risk of rupture. Computed tomography angiography (CTA) is the primary modality for diagnosis, offering precise assessment of anomalous systemic supply, venous drainage, and aneurysmal changes, particularly when complemented with 3-dimensional (3D) reconstruction techniques. We report the case of a 67-year-old male with a history of recurrent pneumonia and intermittent hemoptysis. Imaging revealed left lower lobe intralobar sequestration supplied by an aberrant artery originating from the aortic arch, complica
