Axial (a) and coronal (b) CT images demonstrate erosion of the right jugular bulb, with a moth-eaten appearance of the walls of the right jugular foramen (white arrowheads). This destructive lesion expands into the middle ear, with invasion of the cochlear promontory (white arrow). Axial (c) and coronal (d) T1-weighted post-contrast MR images demonstrate avid enhancement of the mass which arises between the jugular foramen (white arrow) and the cochlear promontory (white arrowhead). The mass fills the jugular foramen and extends into the middle ear anterolaterally
