NEW! We're excited to announce two new radiology learning pathways by Andrew Dixon and Frank Gaillard LEARN MORE

Glomus jugulotympanicum

Case contributed by Assoc Prof Frank Gaillard

A single axial CT bone image through the temporal bones demonstrates a mass arising from the jugular bulb region and extending into the middle ear over the cochlear promontory. The bony margins are irregular and spiculated. 


Single axial and coronal images demonstrate a lobulated enhancing (confirmed on T1C- not shown) mass in the left temporal bone centered on the jugular foramen. 

DSA (angiography)

Left external carotid artery injection demonstrates a high vascular blush consistent with a glomus jugulotympanicum paraganglioma.

Case Discussion

Features on CT, MRI and DSA and consistent are those of a glomus jugulotympanicum paraganglioma. Unfortunately, follow-up and/or histological confirmation are not available.
