CTICasesExpansion of calcified false lumen in chronic aortic dissection
Imaging findings
CT shows a heavily calcified false lumen in a patient with a history of type A dissection repair. Serial CTs show progressive enlargement and outpouching at a site of disrupted wall calcification.
Key takeaways
Although calcified false lumens in chronic dissections are generally stable, focal disruption of the calcified wall can lead to progressive expansion, aneurysm formation, and risk of late rupture.
