  • unusual eustachian tube mass Glomus tympanicum
    American Journal of Neuroradiology, 2001
    Co-Authors: Cheemun Lum, Anne Keller, Edward Kassel, Ralph Blend, John Waldron, John Rutka
    Abstract:

    Summary: A case of recurrent Glomus tympanicum presenting with epistaxis is described. CT and MR imaging revealed a homogeneously enhancing mass extending along the entire course of the eustachian tube, with a portion protruding into the nasopharynx. Glomus tumors tend to spread along the path of least resistance and may extend into the eustachian tube. The unique imaging appearance should place a Glomus tumor high on the list of differential diagnoses.

  • Case Report Unusual Eustachian Tube Mass: Glomus tympanicum
    2000
    Co-Authors: Cheemun Lum, Edward Kassel, Ralph Blend, John Waldron, Anne M. Keller, John Rutka
    Abstract:

    Summary: A case of recurrent Glomus tympanicum pre-senting with epistaxis is described. CT and MR imaging revealed a homogeneously enhancing mass extending along the entire course of the eustachian tube, with a portion protruding into the nasopharynx. Glomus tumors tend to spread along the path of least resistance and may extend into the eustachian tube. The unique imaging appearance should place a Glomus tumor high on the list of differential diagnoses. Glomus tumors of the head and neck have been well described in the radiology and surgical liter-ature. They arise from Glomus bodies, which are chemoreceptors in the temporal bone derived from primitive neural crest cells. The most common, glo-mus jugulare, often presents as an enhancing vas

  • Beyond the promontory: the multifocal origin of Glomus tympanicum tumors.
    American Journal of Neuroradiology, 1998
    Co-Authors: Jane L. Weissman, Barry E. Hirsch
    Abstract:

    PURPOSE: We examined other middle ear locations of Glomus tympanicum tumors, which arise from Glomus bodies accompanying the tympanic (Jacobson's) nerve through the middle ear. Most descriptions place these tumors on the promontory over the basal turn of the cochlea. METHODS: We identified seven patients (all women) with small surgically confirmed Glomus tympanicum tumors (not completely filling the middle ear) for whom CT scans were available for retrospective review. Patients' ages ranged from 23 to 78 years at the time of the high-resolution CT study (1.0- to 1.5-mm-thick sections). RESULTS: All tumors arose on the medial wall of the middle ear. One was anterior to the promontory, beneath the cochleariform process and the semicanal of the tensor tympani. Two were inferior to the promontory, in the recess beneath the basal turn of the cochlea. Four were anteroinferior. None was actually on the apex of the promontory. CONCLUSION: Glomus tympanicum tumors may arise in various locations on the medial wall of the middle ear, where Jacobson's nerve runs. The promontory is only one middle ear location in which Glomus tympanicum tumors may arise. Familiarity with the course of the tympanic nerve helps tailor the search for, and facilitates accurate identification of, tiny Glomus tympanicum tumors.
