Figures & Tables

Figure 1

Angio-CT. Coronal section: The left subclavian artery originates from the aortic arch (arrows) (a); Axial section: Right-sided aortic arch with a left-sided KD (arrows), the left common carotid artery is located anterior to the aortic arch (b); 3D volume-rendered angiographic reconstruction demonstrates a left-sided KD arising from the aortic arch (arrows), continuing into the left subclavian artery (c). CT, computed tomography; KD, Kommerell diverticulum.

Figure 2

Angio-CT, arterial phase; (a) MPR reconstruction shows a KD measuring 28 mm 24 mm (transverse × anteroposterior diameter), with a base (neck) of 24 mm, localized posterior to the trachea and oesophagus, and just anterior to the T7 vertebra; (b) a right-sided aortic arch is visible (arrow); (c) Best exposure of the KD (arrow). CT, computed tomography; KD, Kommerell diverticulum; multi-planar reconstruction (MPR).

Figure 3

The area between the arrows shows the hyperpulsatility of the anterior oesophageal wall.
