Glomus jugulare tumor is a rare, benign paraganglioma of the skull base that forms in the jugular fossa of the temporal bone and is made up of glomus cells which are neural crest cell derivatives.
Presentation
Glomus jugulare tumor (GJT) is uncommon and has been shown to develop primarily between the fourth and seventh decades of life [1] [2]. It has a higher prevalence in females than males and is sometimes inherited familially [1].
Slow growing and non-malignant nature of GJT results in a negative outcome, as the presentation is delayed with gradual onset of symptoms [3]. Symptoms are due to the direct encroachment of the tumor into neighboring structures, and both the size and location of GJT is important for classification purposes [4]. As these tumors arise from the temporal bone, the middle ear is impinged on, causing tinnitus (pulsatile), sensorineural and conductive hearing loss, vertigo, ear discharge, pain, and a reddish-bluish discoloration of the eardrum by an inconspicuous mass on otoscopy. Due to their extensive vasculature, a bruit may be heard upon auscultation of the temporal bone.
The jugular foramen is the aperture through which the internal jugular vein, and cranial nerves IX, X, and XI exit the skull. Compression of the cranial nerves results in dysphagia, hoarseness, change in voice, weakness in the sternocleidomastoid and trapezius muscles leading to the jugular foramen syndrome [2] [5].
The spread of a glomus jugulare tumor into the cranial vault consequently manifests as headaches, accumulation of cerebrospinal fluid and other features of raised intracranial pressure [6]. The brain stem may be affected, giving rise to signs such as loss of coordination, ataxia, loss of balance, and involvement of multiple cranial nerves [6]. Unilateral facial weakness is unusual but has been reported [5].
Most GJTs do not release any hormones. In some instances, however, they secrete adrenalin, noradrenalin, and dopamine, and have been referred to as complex GJTs [7]. Ensuing sympathetic hyperstimulation can induce tachycardia, tachypnea, diaphoresis, and elevated blood pressure; similar to the presentation of adrenal gland tumors. Malignant change is uncharacteristic for these tumors, noted in only a minority of cases [8].

Seizures from temporal lobe penetration by a paraganglioma have been reported, and these tumors have been cited as the cause of cerebral ischemic events, congestive heart failure, and subarachnoid hemorrhage. [neurosurgery.tv]
Workup
Imaging is the mainstay of diagnosis and monitoring in this type of tumor. Computerized tomography (CT) and magnetic resonance imaging (MRI) scans are most frequently used. CT scans and MRI scans help to visualize tumor extension into the bone, as well as spread to adjacent intracranial structures respectively [6]. X-rays of the skull can also be done, and will show signs of abnormal growth around the jugular fossa, but are not as helpful as CT and MRI scans. The aforementioned rich blood supply of glomus jugulare tumors necessitates arteriography and is especially important if tumor resection is planned. Radionuclide scan using meta-iodobenzyl-guanidine (MIBG) has also been used with success, in assessing these masses [9]. If there are indications of sympathetic predominance, urine catecholamine levels can be measured to determine whether tumors are secretory or not [10].
Treatment
Stereotactic radiosurgery for the treatment of Glomus Jugulare Tumors. [surgicalneurologyint.com]
A 47-year-old woman with left ear pain and hearing loss was diagnosed with a glomus jugulare tumor for which she received radiation therapy as the primary treatment. [ncbi.nlm.nih.gov]
At UPMC, the preferred treatment is a transmastoid surgical approach to remove the tumor. In addition, Gamma Knife® radiosurgery may be used as the first treatment option or as an additional treatment after surgery. [upmc.com]

However, treatment may be needed to relieve symptoms. The main treatment is surgery. Surgery is complex and is usually done by both a neurosurgeon and a head and neck surgeon (neurotologist). [sites.magellanhealth.com]

Pathophysiology
PATHOPHYSIOLOGY Benign, Encapsulated, Slow growing, Highly vascular, Locally invasive tumour that erodes bone. Expand within temporal bone via pathways of least resistance – air cells, vascular lumens, skull Base foramina & the eustachian tube. [de.slideshare.net]
Pathophysiology: Glomus tumors are encapsulated, highly vascular, and locally invasive tumors. [drtbalu.co.in]
Pathophysiology The glomera jugulare, or glomus bodies, are small collections of paraganglionic tissue. [emedicine.medscape.com]
Tumors may present a decrease in size, but rarely disappear as observed in pathophysiological analysis of follow-up and radiological tests. [scielo.br]
Prevention
Conductive hearing loss can also occur as the tumor grows into the middle ear space and prevents transmission of sound through the eardrum and ossicular (hearing bone) chain. [neurotucson.com]
In some cases, a procedure called embolization is performed before surgery to prevent the tumor from bleeding too much during surgery. After surgery, radiation therapy may be used to treat any part of the tumor that could not be removed completely. [indiatoday.in]
