1. This postcontrast axial CT image demonstrates the separation of the right IJV and ICA by the SCSC. Tumors of the sympathetic chain usually displace the ICA and IJV together, without separating them.
This postcontrast axial CT image demonstrates the separation of the right IJV and ICA by the SCSC. Tumors of the sympathetic chain usually displace the ICA and IJV together, without separating them.
