Anomalous Systemic Arterial Supply to the Normal Basal Segments of the Left Lower Lobe of the Lung

Abstract

Anomalous systemic arterial supply to the normal basal segments of the lower lobe of the lung without sequestration is a rare congenital abnormality. Whether the condition belongs to the broad spectrum of sequestration disorders remains controversial. This report is of a patient with anomalous systemic arterial supply to the normal basal segments of the left lower lobe, together with an attenuated pulmonary artery and normal tracheobronchial tree.
