Glomus jugulare.A 72-year-old Jehovah's Witness presented with a 1-month history of right-sided neck pain and headache. She was also aware of a slight hearing loss. She had an intermittent "roaring" tinnitus on the right that had begun 5 months earlier. The physical examination revealed the presence of a vascular mass without clearly delineated borders behind her tympanic membrane (figure). During pneumo-otoscopy, the tympanic membrane was brought into contact with the mass. Weber's test was midline, and an audiogram revealed bilateral sensorineural hearing loss Sensorineural hearing loss Hearing loss caused by damage to the nerves or parts of the inner ear governing the sense of hearing. Mentioned in: Tinnitus sensorineural hearing loss that was slightly worse on the right at 3,000, 4,000, and 6,000 Hz. There was no conductive component. The patient had no otalgia, otorrhea, or vertigo, and the lesion was not believed to be causally related to her neck pain or generalized headache. Magnetic resonance imaging magnetic resonance imaging (MRI), noninvasive diagnostic technique that uses nuclear magnetic resonance to produce cross-sectional images of organs and other internal body structures. showed findings typical of a glomus jugulare tumor glomus jugulare tumor n. See chemodectoma. (paraganglioma). The mass extended along the carotid sheath and internal jugular vein internal jugular vein n. A vein that is a continuation of the sigmoid sinus of the dura mater and unites behind the cartilage of the first rib with the subclavian vein to form the brachiocephalic vein. to the inferior border of C2. It filled the carotid sheath and surrounded the right internal carotid artery, displacing the artery anteriorly. Magnetic resonance angiography showed that the mass was highly vascular, and magnetic resonance venography Venography Definition Venography is an x-ray test that provides an image of the leg veins after a contrast dye is injected into a vein in the patient's foot. revealed no flow in the right sigmoid sinus or internal jugular vein. Multiple collateral vessels were seen throughout the neck. The mass was nearly 5 cm in its largest dimension. Because of the patient's age and other health problems, treatment with radiation therapy was elected. Although her status as a Jehovah's Witness enhanced the potential for serious surgical complications, including death, our inability to transfuse trans·fuse v.
