Glomus tympanicum tumors are a rare type of middle ear tumor that often present with symptoms such as pulsatile tinnitus, hearing loss, and ear fullness. (jcohns.org)
Diagnosis2
A high-resolution temporal bone computed tomography (CT) scan demonstrating a contrast-enhancing mass limited to the middle ear at the level of the cochlear promontory with an intact plate of bone at the lateral aspect of the jugular fossa suggests the diagnosis of glomus tympanicum. (medscape.com)
Glomus tumors, also known as non-chromaffin cell paraganglioma, arise from the neural crest cells [1]. (otolaryngrhinojournal.com)
The tympanic nerve may be involved by paraganglioma, in this location referred to as a glomus tympanicum tumour. (wikipedia.org)
Glomus tumors are part of "paraganglioma" family of tumors. (neuroangio.org)
Tumors are diagnosed1
Often, glomus jugulare tumors are diagnosed within the sixth or seventh decade of life and can be followed by imaging only and may not need surgical intervention. (medscape.com)
Pulsatile tinnitus3
Glomus tumors are rare, and the majority do not present with isolated pulsatile tinnitus. (neuroangio.org)
Nevertheless, Glomus Jugulare and Glomus Tympanicum tumors are well-known to cause pulsatile tinnitus. (neuroangio.org)
Rarely tumors may also present with a pulsatile tinnitus, including glomus tympanicum, glomus jugulare, or tumors next to the brain impacting the hearing nerves. (advancedhearingatlanta.com)

Carotid5
Glomus tumors are classified into types depending on where they begin to grow: tympanicum, jugulare, glomus vagale, or carotid body. (otolaryngrhinojournal.com)
Haller introduced glomus tumors of the head and neck into the medical record in 1762 when he described a mass at the carotid bifurcation that had a glomus body-like structure. (naqlafshk.com)
Glomus tumors of the head and neck are associated with 4 primary locations, the jugular bulb, middle ear cavity, vagus nerve, and carotid body. (naqlafshk.com)
Carotid body glomus tumors, also called carotid body tumors, occur at the bifurcation of the common carotid artery and arise from the tissue of the normal carotid body (see the image below). (naqlafshk.com)
Bulb2
Glomus jugulare arise from paraganglia in or around the jugular bulb, and as they grow they occlude this venous structure. (earsite.com)
Nonchromaffin paragangliomas (chemodectomas) arise in the temporal bone from glomus bodies in the jugular bulb (glomus jugulare tumors) or the medial wall of the middle ear (glomus tympanicum tumors). (msdmanuals.com)
Vagale1
Tumors in region of the vagus nerve are commonly called glomus vagale tumors because of their usual close association with the vagus nerve (see the image below). (naqlafshk.com)
Temporal bone2
Temporal bone CT has historically been even better than MRI for glomus, especially glomus tympanicum - an unusual situation since for most tumors MRI is a better test. (neuroangio.org)
In other words, if you've had a negative temporal bone CT and negative MRI brain with contrast, the chances of having a glomus tympanicum or jugulare are pretty much zero. (neuroangio.org)
Paragangliomas2
Imaging is the primary investigative modality for glomus tumors of the head and neck (paragangliomas). (naqlafshk.com)
Paragangliomas, also known as glomus tumors, arise from paraganglion cells which form the basis of the extra-adrenal neuroendocrine system. (springeropen.com)
Arise1
they arise from the glomus bodies that run with the tympanic branch of the glossopharyngeal nerve. (naqlafshk.com)
Resection2
The mainstay of glomus treatment used to be surgical resection. (neuroangio.org)
En bloc resection of the ear canal with sparing of the facial nerve is done when lesions are limited to the canal and have not invaded the middle ear. (msdmanuals.com)
Jugular foramen2
Glomus jugulare ones grow in the jugular foramen, and therefore present with symptoms related to destruction/invasion of adjacent structures. (neuroangio.org)
Cranial nerve palsies of the 9th, 10th, or 11th nerve may accompany glomus jugulare tumors that extend through the jugular foramen. (msdmanuals.com)
Approach1
A study from Vanderbilt University found that in the absence of brainstem compression or concern for malignancy, observation of glomus jugulare tumors can be a viable initial management approach for elderly patients. (medscape.com)
Small2
Glomus tympanicum tumors are small sized tumors originating in the middle ear. (earsite.com)
Standard MRI with contrast and MRA are very good for picking up these tumors, except perhaps a small glomus tympanicum. (neuroangio.org)
Surgery2
Surgery is the treatment of choice for glomus jugulare tumors. (medscape.com)
Of 22 patients with glomus jugulare tumors who underwent Gamma Knife surgery, neurologic status improved in 12 patients, 7 showed stable clinical condition, and 3 patients developed new moderate deficits. (medscape.com)
Symptoms1
If it is in fact a glomus, usually other symptoms are present as well. (neuroangio.org)
Head1
Although glomus tympanicum tumors are the most common primary neoplasms of the middle ear, these tumors are the rarest of head and neck glomus tumors. (naqlafshk.com)
