CTICasesUncorrected Aortic Coarctation in an Adult

Imaging findings
A patient presented with a severe, physiologically complete coarctation of the descending aorta that remained uncorrected into adulthood. Extensive collateral circulation was observed around the chest wall, including markedly dilated intercostal and internal mammary arteries. Associated vertebral segmentation anomalies were also present.
Key takeaways
Severe coarctation of the aorta is a congenital narrowing that, if uncorrected, can lead to significant collateral vessel development to bypass the obstruction, including prominent intercostal and internal mammary arteries. It is less common to see such severe uncorrected coarctation in adulthood, and it is often associated with other congenital anomalies, such as vertebral segmentation defects.
