An aberrant right subclavian artery aneurysm was detected in a 59-year-old patient. He complained of no symptoms, and could not decide whether to accept the operation, so he was carefully treated with antihypertensive drugs at our institution.
Magnetic resonance imaging (Fig 1), digital subtraction angiography (Fig 2), and three-dimensional computed tomographic scan (CT) (Fig 3) showed an aberrant right subclavian artery aneurysm. The three-dimensional CT is very helpful in showing the course of the aneurysm in relationship to its surroundings. The aorta and arch vessel can be seen in brown and the superior vena cava in blue.
