Findings
was changed:
T2 fat saturated and T1 images demonstrating low signal flow voids within a carotid space mass (red arrows) which descends for the jugular foramen. This is the classic "salt and pepper" appearance of paraganglioma.
Axial bone CT shows irregular erosion of bone at the margin of the jugular foramen (yellow arrows) which is a useful feature to help differentiate glomus jugulare paragangliomas from schwannomas which tend to cause smooth remodeling of the foramen.
