In addition to being known as jugulotympanic paraganglioma, the glomus jugulare tumor is a rare type of tumor that usually arises from the paraganglia at the base of the skull near the jugular bulb. The tumors are usually benign and slow-growing, but they can cause significant symptoms due to their proximity to critical brain and neck structures. Here's what you need to know about them:
Causes
It is not clear what causes glomus jugulare tumors. However, it is believed that they result from the glomus cells of the paraganglia, which are specialized cells that regulate blood pressure and blood flow. Tumors may develop as a result of genetic mutations or changes in these cells.
Symptoms
The symptoms of Glomus jugulare tumors are often related to their location and size. Common symptoms include:
-
Hearing loss
-
Tinnitus (ringing in the ears)
-
Dizziness or vertigo
-
Ear pain or fullness
-
Difficulty swallowing
-
Hoarseness or changes in voice
-
Facial weakness or paralysis
-
Headaches
-
Vision changes
-
Neck swelling or mass
Diagnosis
Glomus jugulare tumors are typically diagnosed through imaging studies and specialized tests.
-
In head and neck cancer, magnetic resonance imaging (MRI) is used to visualize the tumor and surrounding structures.
-
CT scan: An imaging test that provides detailed cross-sectional images of the tumor and its surroundings.
-
Angiogram: Visualization of the blood vessels supplying a tumor and assessment of its vascularity.
-
Hearing test to assess auditory function and evaluate hearing loss.
-
A fine needle aspiration biopsy (FNA) involves taking a sample of tumor tissue for microscopic examination and analysis.
Treatment
In addition to the size and location of the tumor as well as the patient's overall health and preferences, treatment options for glomus jugulare tumors include:
-
Small and asymptomatic tumors may be monitored closely without immediate intervention in some cases.
-
This may be accomplished through traditional open surgery or by using minimally invasive techniques such as endoscopic or transnasal surgery.
-
As an adjuvant therapy following surgery or for tumors that cannot be completely removed surgically, radiation therapy targets and destroys cancer cells.
-
The procedure of embolization involves injecting a substance into the blood vessels that feed the tumor to block its blood supply.
Prevention
Currently, there is no known method for preventing glomus jugulare tumors. However, early detection and prompt treatment of symptoms may improve outcomes and reduce complications.
Conclusion
It is a rare and benign tumor that develops near the jugular bulb from the paraganglia. The exact cause is unknown, but it can cause significant symptoms due to its location near critical structures in the head and neck. Early detection and prompt treatment of symptoms are crucial for optimal outcomes, which include imaging studies and specialized tests, as well as surgery, radiation therapy, and embolization.
