The role of CT and MRI in the diagnosis of tympanic and jugular glomus tumors of the temporal bone

Shebunina A.B., Avetisyan E.Ye., Serova N.S.

Glomus tumors of the temporal bone are in most cases benign tumors with locally invasive growth originating from paraganglion cells. The most frequent localizations are the jugular opening (jugular glomus) and the tympanic cavity (tympanic glomus). Glomus tumors make up about 0.6% of all head neoplasms and are the second most common tumors of the temporal bone after schwannoma of the vestibulo-cochlear nerve. CT is possible to establish the exact localization of formation, and at later stages of the disease to assess its distribution in the mastoid process, infraralabyrinth space, auditory tube up to the wall of the carotid artery; evaluate the preservation of the walls of the tympanic cavity, the posterior wall of the pyramid, the walls of the bone channel of the carotid artery. When the tumor spreads into the hypothypanum, MRI is required to exclude involvement of the jugular vein bulb. This literature review describes the current capabilities of computed tomography and magnetic resonance imaging of the temporal bones in the diagnosis of glomus tumors.
