Imaging findings
An 82-year-old male with chronic, asymptomatic consolidation in the right lower lobe showed a distinct pleural surface and some aeration within the abnormality. CT confirmed a pulmonary sequestration with a calcified systemic arterial feeder running directly from the aorta into the sequestered lung segment.
Key takeaways
Pulmonary sequestration involves a non-functioning segment of lung with an anomalous systemic arterial supply. The presence of a calcified arterial feeder, even in elderly patients, is a characteristic finding. These systemic arteries supplying sequestrations tend to show earlier sclerosis and calcification compared to the general vasculature.
