CTICasesPulmonary Sequestration
Imaging findings
Recurrent left lower lobe pneumonias are associated with a persistent consolidation and volume loss in the left lower lobe. No feeding vessel from the aorta is visible, suggesting a potential thrombosed sequestration or hybrid CPAM lesion.
Key takeaways
Recurrent pneumonia in the same lung segment in a young patient should prompt suspicion of a congenital lung abnormality, such as a pulmonary sequestration or hybrid CPAM. The feeding systemic artery may occasionally thrombose, making identification difficult on imaging.
