sinus nerve, or Hering's nerve: the branch of the glossopharyngeal nerve to the carotid sinus is the nerve that runs downwards anterior to the internal carotid artery communicates with the vagus and sympathetic then divides in the angle of bifurcation of the common carotid artery to supply the carotid body and carotid sinus; it carries impulses from the baroreceptors in the carotid sinus (to help maintain more consistent blood pressure) and from chemoreceptors in the carotid bod Glossopharyngeal neuralgia is rare but causes severe pain. We retrospectively evaluated preoperative MR images of patients with glossopharyngeal neuralgia caused by neurovascular compression. CONCLUSION. MRI may be beneficial in patients with glossopharyngeal neuralgia and an offending compressing artery

Glossopharyngeal Neuralgia. A primary function of the glossopharyngeal (9th cranial) and vagus (10th cranial) nerves is to carry sensation from a number of structures around the back of the throat to the brainstem. Abnormal functioning of these nerves in glossopharyngeal neuralgia (GPN) patients, however, results in severe bouts of shock-like pain. Similarly, viral pathologies may account for glossopharyngeal nerve or, rarely, ac- cessory nerve pathologies. Idiopathic involvement of the cranial nerve IX, termed glossopharyngeal neuralgia, is uncommon, and can result in soft palate elevation when accompanied by vagus nerve dysfunction. Idiopathic accessory nerve paralysis is rare Axial oblique .8-mm-thick SSFP MR image shows the vagus nerve (arrow) where it crosses the lateral cerebellomedullary cistern (LCM) and approaches the jugular foramen. The vagus and glossopharyngeal nerves, which are difficult to distinguish in this plane, are clearly distinguishable in the coronal oblique plane (see , Fig 17) Object. The aim of this study was to determine whether high-resolution MR imaging is suitable for identifying and differentiating among the nerve root bundles of the glossopharyngeal (cranial nerve [CN] IX), vagus (CN X), and accessory nerves (CN XI) as well as any adjacent vessels The contact points were the REZ of the glossopharyngeal nerve in 3 patients and the PNS segment in 4 patients. 1-3. Presence or absence of a shift of the glossopharyngeal nerve at the contact point . In 6 of 7 cases, the shift of the glossopharyngeal nerve at the contact point was found in MRI. 1-4
High-resolution MRI at 3 tesla demonstrated the posterior inferior cerebellar artery to be closely related to the rootlets of the left glossopharyngeal nerve in a patient who suffered attacks of. nerve: A single fiber of the glossopharyngeal nerve is located in the anterior part of the jugular foramen . The attachments of the glossopharyngeal nerve with offending vessels were then identified on 3D-T2R and CISS with reference to the operative charts. Finally, the distance between the glossopharyngeal nerve While a plethora of sensory branches exist around the face and neck and can be associated with or implicated in pain syndromes, the larger and commonly imaged and/or treated nerves below the skull base include the PTN and its branches, facial nerve, glossopharyngeal nerve, vagus nerve, hypoglossal nerve, supraorbital nerve, greater occipital nerve (GON), and lesser occipital nerve (LON)

The abnormal glossopharyngeal nerve contrast enhancement suggests inflammatory changes, possibly induced by irritation secondary to arterial pulsations on the nerve. Download figure. Magnetic resonance imaging (MRI) is very useful for initial screening in GPN cases and for preoperative imaging assessment to identify offending vessels, their course, and contact points and to characterize the condition of the glossopharyngeal nerve. MR images with three-dimensional data acquisition (3D-MRI) are recommended, and they include.
A total of 168 nerves were investigated. The rates for visualization for each nerve were as follows: glossopharyngeal nerve, 100% and 100%; vagus nerve, 67.9% and 100%; and accessory nerve, 10.8%. imaging (MRI) with a sequence of constructive interfer-ence in steady state (CISS) showed the compression of the glossopharyngeal nerve by the posterior inferior cerebellar artery (PICA). Further, no abnormal findings were noted in the otorhinolaryngologic and other cranial nerve examinations. Moreover, there were no signs of Eagle's syndrome Browse 10 glossopharyngeal nerve stock photos and images available, or search for gastrocnemius to find more great stock photos and pictures.

Glossopharyngeal neuralgia is a rare condition with neuralgic sharp pain in the pharyngeal and auricular region. Classical glossopharyngeal neuralgia is caused by neurovascular compression at the root entry zone of the nerve. Regarding the rare occurrence of glossopharyngeal neuralgia, we report clinical data and magnetic resonance imaging (MRI) findings in a case series of 19 patients, of.
The glossopharyngeal nerve originates in the medulla oblongata of the brain. It emerges from the anterior aspect of the medulla, moving laterally in the posterior cranial fossa. The nerve leaves the cranium via the jugular foramen. At this point, the tympanic nerve arises. It has a mixed sensory and parasympathetic composition Schwannoma arising from the glossopharyngeal nerve is a rare intracranial tumor. Fewer than 40 cases have been reported. Accurate pre-operative diagnosis and optimal treatment are still difficult. We present one case of schwannoma originating from the ninth cranial nerve with palsies of the trigeminal nerve, facial-acoustic nerve complex, and vagus nerve in addition to ninth nerve dysfunction Glossopharyngeal neuralgia (GPN) is believed to be caused by irritation of the ninth cranial nerve, called the glossopharyngeal nerve. Symptoms usually begin in people over age 50. In most cases, the source of irritation is never found. Possible causes for this type of nerve pain (neuralgia) are: Blood vessels pressing on the glossopharyngeal nerve
The glossopharyngeal nerve (CN IX) at the ventrolateral medulla oblongata features a complex formation in the posterior cranial fossa. The CN IX emerges from the retro-olivary sulcus in the region of the flower basket of Bochdalek and superiorly courses to the vagus nerve to the jugular foramen Glossopharyngeal neuralgia can be diagnosed symptomatically however the for confirming the cause of the compression of the nerve various tests are required like blood tests, MRI and X ray of head and neck

Rarely are other cranial nerves involved, in descending order of frequency it is the fifth nerve, seventh nerve and twelfth nerve.  The usual symptoms of glossopharyngeal schwannomas include hearing loss, tinnitus vertigo, gait ataxia, headache, nystagmus, hoarseness, palate-pharyngeal and facia hypoestesia, rarely papilloedema and dysphagia. [3 Glossopharyngeal neuralgia is generally caused by a small blood vessel that presses on the nerves as they exit the brainstem. This condition is caused by irritation of the ninth cranial nerve by a blood vessel, and is most commonly seen in people over age 40 Glossopharyngeal Neuralgia (GPN) Glossopharyngeal neuralgia (GPN) is a rare condition that can cause sharp, stabbing, or shooting pain in the throat area near the tonsils, the back of the tongue or the middle ear. The pain occurs along the pathway of the glossopharyngeal nerve, which is located deep in the neck
We present the case of a 13-year-old female with MRI confirmed Bell's palsy (facial; facial paralysis) with associated involvement of cranial nerves 5 (trigeminal; decreased sensation), 9/10 (glossopharyngeal/vagus; difficulty swallowing), and 12 (hypoglossal; tongue deviation). A 13-year-old African-American female presented to the emergency. Glossopharyngeal Neuralgia. Glossopharyngeal neuralgia (GN) is a rare pain syndrome that affects the glossopharyngeal nerve (the ninth cranial nerve that lies deep within the neck) and causes sharp, stabbing pulses of pain in the back of the throat and tongue, the tonsils, and the middle ear Normal left glossopharyngeal and vagus nerves were observed. MR angiography of major intracranial arteries demonstrated a tortuous vascular loop of the right PICA in the right cerebellopontomedullary angle. Once the diagnosis of GPN had been made, the patient was commenced on amitriptyline. The symptoms were improved after starting the medication Hur diagnostiseras Glossopharyngeal Nerve Schwannoma?
