An axial CT of the neck revealing an oval heterogeneous mass in the right carotid space measuring 35 x 24 x 28 mm. The internal jugular vein (blue arrow) is displaced laterally and the common carotid artery (red arrow) is displaced anteriorly leading to the spaying seen. This is often a characteristic sign of VNS.
