CTICasesIntralobar Pulmonary Sequestration
Imaging findings
Chest CT shows a relatively small, solid soft tissue mass in the medial left lower lobe associated with focal hyperinflation. A large anomalous congenital systemic artery is seen arising directly from the descending thoracic aorta and entering the mass.
Key takeaways
Intralobar pulmonary sequestration can present as a small, non-cystic area of consolidation or hyperlucent lung tissue. Identifying the feeding systemic artery from the aorta is key to differentiating it from other lung masses.
