ABSTRACT

Diagnosis: Glomus jugulare tumor (presumptive - no biopsy)

History: 78 yo male with prior history significant for squamous cell carcinoma (T1N0M0) of the true vocal cord 20 years prior now with loss of hearing in the left ear for several months

Findings: Large tumor of the left vascular space which displaces adjacent vessels. Condylar and basilar portions of the occipital bone are eroded. The lesion is slightly hypointense to gray matter on T1 and vigorously enhances following contrast administration. A salt and pepper appearance is noted.

Ddx: Glomus jugulare - most likely given slow growth, "salt and pepper" appearance with contrast, and vigorous contrast enhancement Schwannoma - delayed enhancement and prolongedcontrast properties not characteristic Meningioma - delayed imaging was not performed thus cannot rule out based on enhancement characteristics alone

Exam: Sensorineural hearing loss.

No MeSH data available.


AX T1 sequence shows the mass eroding a portion of the left occipital bone (condylar portion) and both the mastoid and petrous portions of the temporal bone. There is near complete effacement of the precerebellar cistern. The internal jugular vein is displaced anteriorly and in some portions narrowed (not shown). Also the petrous portion of the ICA is completely encased without narrowing.
