CTICasesAnatomic variant of right lung abutting the ascending aorta
Imaging findings
CT scan shows the right upper lobe lung directly contacting the right lateral margin of the ascending aorta, which is a normal anatomical variant.
Key takeaways
Normally, mediastinal fat, the SVC, and the right atrial appendage prevent direct contact between the right lung and ascending aorta. Appreciating this normal variant is important to prevent misinterpreting it as pathology.
