    Posteroanterior chest radiograph shows a right-sided paratracheal soft tissue density mass behind the medial end of the right clavicle.

     
    Area of Interest: unknown; Imaging Technique: Figure 1;

    Axial CT image with contrast shows aneurysmatic dilatation of the right aberrant subclavian artery with hypodense mural thrombus. It causes compression on the trachea and esophagus.

ECG-gated T2-weighted spin echo axial MR image of the chest reveals a partially thrombosed aneurysm of an aberrant right subclavian artery arising from a diverticulum of Kommerell, crossing the midline behind the trachea and esophagus coursing to the right side. The hyperintense signal in the patent lumen is related to slowed and complex flow resulting from the aneurysm.

Oblique coronal MIP image of MR angiography shows the aneurysm of aberrant right subclavian artery originating from diverticulum of Kommerell, the whole dimension of the aneurysm cannot be accessed due to mural thrombus. The bicarotid trunk variant is also associated.
