Both types of glomus tumour can cause pulsatile tinnitus in 60 of patients. Glomus jugulare paraganglioma is a paraganglioma of the head and neck that is confined to the jugular fossa. While it is a rare tumour, it is the most common of the jugular fossa tumours. When significant involvement is present then the lesion may cause pulsatile tinnitus and hearing loss. Up to 10 of the patients may have multiple lesions. Learn more about Paragangliomas (Glomus Tumors), diagnosis, symptoms, treatment options and information at Mount Sinai. Glomus jugulare arise from paraganglia in or around the jugular bulb. They are usually nonsecretory but occasionally produce and secrete proteins into the bloodstream that can cause symptoms such as high blood pressure, rapid heart rate, tremor, sweating and headache.
Both types of glomus tumor can cause pulsatile tinnitus in 60 of patients. Unilateral or pulsatile tinnitus may be caused by more serious pathology and typically merits specialized audiometric testing and radiologic studies. In patients who are discomforted by tinnitus and have no remediable cause, auditory masking may provide some relief. Objective tinnitus can be heard through a stethoscope placed over head and neck structures near the patient’s ear. Glomus tumor is a vascular neoplasm arising from the paraganglia around the carotid bifurcation, the jugular bulb, or the tympanic arteries. 2000;61:274956,275960. Causes and treatment of pulsatile ear ringing or tinnitus. A carotid ultrasound can test for carotid plaques which can cause pulsatile tinnitus and if obstructive or friable may cause a stroke. These tests may find vascular malformations and vascular tumors, such as a glomus tympanicum or jugulari. CT Scan in a Patient with a Diverticulum of the Internal Jugular Vein.
Local tumor control rates after surgery for glomus jugulare and tympanicum tumors vary from 20 to 95 with most authors reporting 80-90 control rates. Invasion of nearby structures: Posterior fossa extension and growth can lead to brainstem dysfunction due to tumor mass compression. Three patients reported improvement in their pulsatile tinnitus. Most patients with glomus tumors of the middle ear can hear a pulsing sound in the ear on the side which has the tumor. Pulsatile tinnitus occurs as the tumor enlarges and presses against the bones of hearing. However, in small glomus tumors of the middle ear, hearing can be quite normal and there may be no symptoms at all. In 1996, the patient developed pain in his lower thoracic spine. The glomus jugulare was first described in 1840 by Valentin4 as the ganglia tympanica. Although most paragangliomas are sporadic, they can be familial with autosomal dominant inheritance and incomplete penetrance. 1 year after the initial symptoms of hearing loss and pulsatile tinnitus.

We report a case of secretory glomus jugulare tumor in a 65 year old female who presented with hearing impairment, pulsatile tinnitus, from 3 years and difficulty in swallowing, hoarseness of voice and palpitation from last six months. A 65 year old lady, reported with chief complaints of impairment of hearing right ear and pulsatile tinnitus from last three years with difficulty in swallowing and hoarseness of voice, palpitation from last six months. Common causes of conductive hearing loss include wax accumulation, ear drum rupture, infections of the outer or middle ear, stiffening or fixation of the small middle ear bones, cholesteatoma (abnormal accumulation of skin in the middle ear), and other less common causes including superior semicircular canal dehiscence syndrome and malformations of the middle or inner ear bony architecture. This can associated with a feeling of fullness or pressure in the ear, tinnitus (ringing), distortion of speech and sound, and often times dizziness and/or vertigo. We report a glomus jugulare tumor in a 60 yrs old female; non diabetic, non hypertensive who presented with continuous pulsatile hissing tinnitus in right ear with progressive hearing impairment and fullness in the ear. Patient was treated successfully by surgical excision of tumor. Cochleovestibular destruction is caused by ischemic necrosis. Five patients died during follow-up due to old age or other, not treatment-related reasons. LINAC-Radiosurgery can achieve an excellent long-term tumor control beside a low rate of morbidity in the treatment of GJTs. Most of the patients present with pulsatile tinnitus, conductive hearing loss, dizziness and dysfunction of the cranial nerves V, VII and IX-XII. 1993;103(11 Pt 2 Suppl 60):715.
