A rare case of pulmonary sequestration with pulmonary drainage into the left renal vein

Abstract

Extralobar pulmonary sequestration (ELS) is a nonfunctional lung tissue that has no relationship to the tracheobronchial tree, abnormal arterial supply from the aorta, and venous drainage into the systemic vein. We provide a very unusual instance of ELS in a newborn with venous drainage into the left renal vein, emphasizing the need to include ELS in the differential diagnosis of congenital lung lesions and meticulous verification of arterial supply and venous drainage before surgical resection. © 2025 The Author(s); Published by Society of Diabetic Nephropathy Prevention.
