What is Globus Jugularis?

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.

Are glomus tumors cancerous?

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.

What is glomus jugulare paraganglioma?

Glomus jugulare is a slow-growing paraganglioma of the head and neck that arises within the jugular foramen and localized to the jugular fossa. Paragangliomas are benign and are originated from neural crest derivatives, known as the paraganglia.

Where is a glomus tumor located?

Glomus tumor is a slow-growing, vascular tumor located at the skull base. Also known as a glomus jugulare, glomus tumor is the most common tumor of the temporal bone, which contains the middle and inner portions of the ear.

Can glomus tumors cause tinnitus?

Glomus tumors may cause hearing loss or pulsating tinnitus. Glomus tumors characteristically affect hearing because they often are located within or adjacent to the temporal bone. Involvement of the ossicles may cause a conductive hearing loss.

Can glomus tumors cause vertigo?

Most glomus tumors are asymptomatic. However, they may cause pain (especially in the subungual location), hearing loss (ear), pulsatile tinnitus, dizziness, or cranial nerve palsies (ear or cranial nerves).

Is glomus tumor painful?

Glomus tumors are painful subungual lesions. They produce a throbbing or lancinating local discomfort, cold-sensitivity, and severe pain following minor trauma. The diagnosis is confirmed by histology, but the clinical diagnosis is highly suggestive. Complete excision will usually relieve pain.

What type of tumor causes vertigo?

Acoustic neuroma, also known as vestibular schwannoma, is a noncancerous and usually slow-growing tumor that develops on the main (vestibular) nerve leading from your inner ear to your brain.
