Imaging findings
Chest radiograph and CT show severe, diffuse lung destruction consistent with panlobular emphysema in a non-smoker, associated with an ascending aortic aneurysm and a history of prior aortic valve and aortic root replacement.
Key takeaways
Vascular Ehlers-Danlos syndrome (Type IV) is a rare autosomal dominant connective tissue disorder caused by mutations in the COL3A1 gene. In addition to a high risk of life-threatening arterial dissection and rupture, it is an under-recognized cause of early-onset panlobular emphysema and cystic lung disease in young non-smokers, serving as a unifying diagnosis for concurrent vascular and parenchymal abnormalities.
