1 A, Contrast-enhanced axial CT scan shows lipomatous regions with thick septa (white arrow), a low-attenuation high-water-content component (black arrow), and sporadic heterogeneous high-attenuation calcified areas in the right common carotid space. A, Contrast-enhanced axial CT scan shows lipomatous regions with thick septa (white arrow), a low-attenuation high-water-content component (black arrow), and sporadic heterogeneous high-attenuation calcified areas in the right common carotid space. The mass surrounds the right common carotid artery and displaces the jugular vein (black arrowhead) laterally. B, In this precontrast axial CT scan with a bone algorithm, the tumor ossification (black asterisks) is evident. C, A multiplanar reformatted image shows the mass with well-defined margins between the sternocleidomastoideus muscle and the lateral pharyngeal wall, displacing the right jugular vein. Thick septa (white arrows) and fat (white asterisks) are noted. Y. Wang, and H. Shi AJNR Am J Neuroradiol 2012;33:E4-E6 ©2012 by American Society of Neuroradiology
