View larger version (171K): [in a new window]   Fig. 1A. —Primary jugular foramen meningioma in 60-year-old woman. Coronal unenhanced T1-weighted image shows mass centered in jugular foramen (star) with extensive surrounding infiltration of skull base. Note medial infiltration into jugular tubercle and occipital condyle with replacement of normal hyperintense marrow (solid arrow), spread into posterior fossa and into internal auditory canal (open arrow), lateral spread into middle ear cavity, and inferior involvement of nasopharyngeal carotid space. Also note absence of high-velocity flow voids.

View larger version (170K): [in a new window]   Fig. 1B. —Primary jugular foramen meningioma in 60-year-old woman. Coronal contrast-enhanced fat-saturated T1-weighted image obtained slightly anterior to A shows intense enhancement and extensive infiltration of surrounding skull base. Note spread into posterior fossa (thin black arrow), lateral spread into middle ear cavity (white arrow), and inferior involvement of nasopharyngeal carotid space (thick black arrow).

View larger version (168K): [in a new window]   Fig. 1C. —Primary jugular foramen meningioma in 60-year-old woman. Axial contrast-enhanced fat-saturated T1-weighted image shows en plaque involvement of posterior fossa with prominent dural tails, medial spread in skull base to mid clivus (solid arrow), and tumor in middle ear cavity that engulfs ossicles (open arrow).

View larger version (162K): [in a new window]   Fig. 1D. —Primary jugular foramen meningioma in 60-year-old woman. Bone window image from unenhanced axial CT scan shows margins of jugular foramen (star) to be slightly irregular with loss of normal cortex. Infiltrated skull base shows relatively well-preserved bone density and bone architecture, resulting in characteristic permeative–sclerotic appearance.

View larger version (159K): [in a new window]   Fig. 2B. —Jugular foramen paraganglioma in 44-year-old woman. Coronal contrast-enhanced fat-saturated T1-weighted image shows intensely enhancing mass centered in jugular foramen (star) with superolateral spread into hypotympanum (arrow). Spread into posterior fossa and medial skull base is limited.

View larger version (150K): [in a new window]   Fig. 2C. —Jugular foramen paraganglioma in 44-year-old woman. Bone window image from unenhanced coronal CT scan shows permeative erosion of margins of jugular foramen (arrow) without sclerosis. Note soft tissue in hypotympanum.

View larger version (183K): [in a new window]   Fig. 3A. —Jugular foramen schwannoma in 53-year-old man. Axial contrast-enhanced fat-saturated T1-weighted image shows intensely enhancing well-circumscribed jugular foramen mass (star) with extension into posterior fossa (arrow) toward lateral medulla. No skull base infiltration is present.

View larger version (177K): [in a new window]   Fig. 3B. —Jugular foramen schwannoma in 53-year-old man. Sagittal contrast-enhanced T1-weighted image shows inferior involvement of nasopharyngeal carotid space with anterior displacement of carotid artery (arrow).

View larger version (156K): [in a new window]   Fig. 3C. —Jugular foramen schwannoma in 53-year-old man. Bone window image from unenhanced axial CT scan shows expansion of jugular foramen with preservation of cortex (arrow). No bone infiltration is present.

View larger version (103K): [in a new window]   Fig. 4A. —Typical growth patterns of primary jugular foramen meningioma, paraganglioma, and schwannoma. (Reprinted with permission from [10]) Drawing shows primary jugular foramen meningioma with centrifugal infiltration surrounding skull base including lateral spread into hypotympanum, medial spread into jugular tubercle and hypoglossal canal, inferior involvement of carotid space, and dural-based involvement of posterior fossa.

View larger version (103K): [in a new window]   Fig. 4B. —Typical growth patterns of primary jugular foramen meningioma, paraganglioma, and schwannoma. (Reprinted with permission from [10]) Drawing shows jugular foramen paraganglioma as vascular mass infiltrating surrounding skull base with superolateral growth into hypotympanum of middle ear cavity.

View larger version (109K): [in a new window]   Fig. 4C. —Typical growth patterns of primary jugular foramen meningioma, paraganglioma, and schwannoma. (Reprinted with permission from [10]) Drawing shows jugular foramen schwannoma as well-circumscribed fusiform mass with superomedial growth toward lateral medulla along course of cranial nerves 9–11. Jugular foramen is enlarged with well-corticate bone margins.
