CTICasesIntralobar Bronchopulmonary Sequestration with Premature Atherosclerosis
Imaging findings
Serial CT scans over 10 years in a young female show a cystic right lower lobe mass supplied by a large, systemic arterial feeder arising from the inferior phrenic artery at the diaphragm. Pathology confirmed intralobar sequestration with premature atherosclerosis in the systemic feeder.
Key takeaways
Intralobar sequestration is a congenital abnormality of the lung that receives systemic arterial supply. Premature atherosclerosis is a classic histopathologic finding in the systemic feeder due to high-flow vascular stress and turbulent flow under systemic pressures in a low-resistance pulmonary venous system.
