Imaging findings
A focal hypodense area in the left lower lobe, distinct from normal lung, with a large systemic vessel (from the aorta) supplying it. The systemic arterial supply is key.
Key takeaways
Intralobar pulmonary sequestration is a congenital anomaly where a portion of the lung is supplied by a systemic artery rather than the pulmonary circulation.
