CTICasesSystemic Arterialization to the Left Lower Lobe
Imaging findings
A large systemic artery off the aorta supplying the left lower lobe, effectively replacing the pulmonary artery.

This distinct pattern involves a systemic artery originating near the hilum, imitating the attachment of a normal pulmonary artery. It is differentiated from sequestration by the presence of normal communication with the central airways.
