  • Radiopaedia case ID: 21423
  • Image ID: 2876282
  • Image stack position: 16/60
  • Plane projection: Axial
  • Aux modality: MRA
  • Modality: MRI

  • Findings: MR angiogram with gadolinium demonstrates an aberrant right subclavian artery (arrowed). Note normal loss of signal (flow void) due to blood changing direction within the descending aorta. Also, note the associated aneurysmal dilatation of this vessel. Coronal MR angiogram further demonstrates the aberrant origin of the right subclavian artery. Incidental gallstone noted (arrowed). 3D rendered image demonstrates the aberrant subclavian anatomy. In addition, there is considerable pruning and stenoses with areas of occlusion involving the subclavian arteries more distally (arrowed).
