Presentation transcript:

Axial contrast-enhanced CT (A) and sagittal contrast-enhanced reformatted (B) images reveal a well-defined ovoid mass with homogeneous intense enhancement. Axial contrast-enhanced CT (A) and sagittal contrast-enhanced reformatted (B) images reveal a well-defined ovoid mass with homogeneous intense enhancement. The degree of enhancement is as intense as that of vascular structures. The mass is located posterolateral to the internal and common carotid arteries (arrow) and the compressed internal jugular vein (open arrow). These structures are displaced anteromedially by the mass. S.K. Lee, and S.Y. Kwon AJNR Am J Neuroradiol 2009;30:1604-1606 ©2009 by American Society of Neuroradiology
