1. The postcontrast axial CT image shows the SCSC as a hypoattenuated mass with poor enhancement.
The postcontrast axial CT image shows the SCSC as a hypoattenuated mass with poor enhancement. There is posterolateral displacement of the right ICA and IJV. This is unlike the anterior displacement of the ICA that is normally seen in carotid space masses (compare with the earlier figures). However, true to its carotid space location, there is anterior displacement of the fat in the prestyloid parapharyngeal space, and it displaces the visceral space medially.
