What is a jugular foramen meningioma?
What is a jugular foramen meningioma?
The jugular foramen is an unusual location of meningiomas and can represent primary or extension of intracranial meningioma. Primary jugular foramen meningioma (PJFM) presumably arises from arachnoid villi associated with the jugular bulb and is more frequent in women (2:1).
What is the jugular fossa?
The jugular fossa is a depression situated on the inferior surface of the petrous temporal bone posterior to the inferior opening of the carotid canal. It lodges the jugular bulb. Anteriorly lies the jugular foramen.
What cranial nerve runs through jugular foramen?
Cranial nerves IX, X, and XI, originate from the brainstem and exit the cranium via the jugular foramen. These nerves originate from the medulla, the inferior most portion of the brainstem.
What would be a potential symptom of a patient developed a tumor at the jugular foramen?
The jugular foramen is on the temporal bone. The temporal bones are on the sides of your skull, or your temples. These tumors are nearly always benign, or noncancerous, but their presence can cause hearing loss, problems with swallowing, and facial paralysis.
What goes through jugular foramen?
The structures that traverse the jugular foramen are the sigmoid sinus and jugular bulb, the inferior petrosal sinus, meningeal branches of the ascending pharyngeal and occipital arteries, the glossopharyngeal, vagus, and accessory nerves with their ganglia, the tympanic branch of the glossopharyngeal nerve (Jacobson’s …
What goes through jugular canal?
Intradurally, the glossopharyngeal, vagus, and accessory nerves leave the intracranial compartment through the jugular foramen. These nerves leave the medulla and upper cervical spinal cord and transverse the lateral cerebellomedullary cistern before entering the jugular foramen (Figure 6).
What happens if jugular foramen is damaged?
Clinical features depend on the structures affected by JFS[21]: Vagus: Vagal compression initially causes paralysis of the laryngeal muscles leading to hoarseness and a nasal pitch. If the nerve gets compressed further, it results in unilateral paralysis of the soft palate and deviation of the uvula to the normal side.
How is glomus tumor treated?
The curative treatment of choice for symptomatic solitary glomus tumors is total surgical excision to minimize the rate of painful recurrence. There have been reports that laser and sclerotherapy may be effective in some cases of solitary glomus tumors however, complete excision is the best option.
Where is the jugular foramen located and which structure passes through it?
A jugular foramen is one of the two (left and right) large foramina (openings) in the base of the skull, located behind the carotid canal. It is formed by the temporal bone and the occipital bone….

Which of the following does not pass through the jugular foramen?
The hypoglossal nerve does not traverse the jugular foramen; however, it joins the nerves exiting the jugular foramen just below the skull base and runs with them in the carotid sheath.
Why is the foramen magnum important?
The foramen magnum functions as a passage of the central nervous system through the skull connecting the brain with the spinal cord.
