An overlooked “bud” of an aortic aneurysm on a chest radiography resulted in a saccular aortic aneurysm 9 years later. This eye‐catching image showed us the importance of not only documenting abnormalities in regular radiography but also further imaging evaluation for definitive diagnosis and continuous image follow‐up. A chest radiography plays an important role to detect an early sign of critical diseases. In this case, thoracic aortic aneurysm “buds” in the chest radiography was overlooked and it enlarged later. It is important for physicians not only to document abnormal findings but also make close inspection.
