Is glomus jugulare a brain tumor?

Is glomus jugulare a brain tumor?

Brain and Skull Base Tumors Glomus jugulare tumors are rare growths that arise in the jugular foramen of the temporal bone near the skull base. Common surgical treatments for glomus jugulare tumors are craniotomy and endoscopic endonasal surgery, and nonsurgical treatment is stereotactic radiosurgery.

How is glomus jugulare treated?

Surgery is the treatment of choice for glomus jugulare tumors. However, radiation therapy, particularly stereotactic radiosurgery (eg, Gamma Knife surgery), has been shown to provide good tumor growth control with a low risk of treatment-related cranial nerve injury.

Can glomus tumors cause tinnitus?

Theses are rare, benign, but highly vascular tumours that can affect the ear, skull base and neck. In the head and neck area, most commonly they present with pulsatile tinnitus (a whooshing sound in the ear in time with the pulse), and or a hearing loss.

What does glomus jugulare mean?

A glomus jugulare tumor is a tumor of the part of the temporal bone in the skull that involves the middle and inner ear structures. This tumor can affect the ear, upper neck, base of the skull, and the surrounding blood vessels and nerves.

Is glomus Jugulare benign?

Glomus tumors, or paragangliomas, are slow-growing, usually benign tumors in the carotid arteries (major blood vessels in your neck), the middle ear or the area below the middle ear (jugular bulb). Glomus tumors are most often benign; however, they can cause significant damage to surrounding tissues as they grow.

Is glomus Jugulare hereditary?

However, in some families, multiple relatives are affected by glomus jugulare tumors, which indicates there may be an inherited risk factor ( genetic predisposition ) that increases the chance of developing this disease.

What type of tumor causes pulsatile tinnitus?

Head and Neck Tumors Glomus tumors may grow into the middle ear and brain. When these tumors press on the blood vessels in the head or neck, they can cause pulsatile tinnitus and other symptoms. Glomus tumors are highly vascular and can cause also pulsatile tinnitus just by being in close proximity to the ear.

What is glomus Tumour?

Glomus tumor is a benign mesenchymal neoplasm comprising less than 2% of soft tissue tumors. It is composed of cells resembling modified smooth muscle cells of the normal glomus body. The glomus body, a thermoregulator, is a specialized form of arteriovenous anastomosis localized in dermal and precoccygeal soft tissue.

Is glomus jugulare hereditary?

What is the pathophysiology of glomus jugulare tumors?

Glomus jugulare tumors are defined according to the location (i.e. origin at the jugular foramen) rather than the anatomic origin and may arise from Jacobson nerve, Arnold nerve, or the jugular bulb 3. Tumors may be bilateral, and other tumors such as carotid body tumors may coexist. Up to 10% of the patients may have multiple lesions.

What is the long-term follow-up for glomus jugulare (jugulare)?

Glomus jugulare are slow-growing tumors; therefore, long-term follow-up is necessary. Follow-up is given by an interprofessional team, which should include primary care physicians, neurosurgeons, otolaryngologists, and neuroradiologists.

What are the signs and symptoms of glomus jugulare?

Glomus jugulare patients may exhibit non-specific signs and symptoms such as tinnitus and decreased hearing. At first, diagnosis may be challenging to recognize.

What are the treatment options for glomus jagulare tumor (GJ)?
