Glomus Jugulare Tumour


Glomus jugulare tumors are rare, slow-growing, hypervascular tumors that arise within the jugular foramen of the temporal bone. They are included in a group of tumors referred to as paragangliomas, which occur at various sites and include carotid body, glomus vagale, and glomus tympanicum tumors. Axial and coronal computed tomography (CT) scanning with thin sections are superior at demonstrating the extent of bone destruction. Magnetic resonance imaging (MRI) with contrast is best for delineating tumor limits. Glomus tumors on T1- and T2-weighted MRI have characteristic soft tissue mixed intensity with intermixed high-intensity signals and signal voids (salt and pepper appearance) representing fast flowing blood.
