Glossopharyngeal nerve Radiology Reference Article

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

  2. The glossopharyngeal nerve ( / ˌɡlɒsoʊfəˈrɪn ( d) ʒiəl, - ˌfærənˈdʒiːəl / ), known as the ninth cranial nerve ( CN IX ), is a mixed nerve that carries afferent sensory and efferent motor information. It exits the brainstem out from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve
  3. MRI may be beneficial in patients with glossopharyngeal neuralgia and an offending compressing artery. If the offending vessel was the posterior inferior cerebellar artery (PICA), a loop formation at the supraolivary fossette was always seen, whereas if it was the anterior inferior cerebellar artery (AICA), glossopharyngeal neuralgia was difficult to diagnose before surgery

Do we know where to look at the glossopharyngeal nerve

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.

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)

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.

Highly focused beams of radiation are delivered to the nerve root Clarifying temporal changes in magnetic resonance imaging (MRI) offers a good chance to understand the pathology of neural lesions; however, such information is scarce in varicella zoster virus (VZV) neuropathies for the glossopharyngeal and vagus nerves. Here, we present the changes in sequential MR images of such a pathology over a period of 12 months from symptom onset.A 27-year-old woman. Because the glossopharyngeal nerve is smaller than the trigeminal nerve, it is more difficult to localize.

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
