Glossopharyngeal Neuralgia Caused by Arachnoid Cyst in the Cerebellopontine Angle

Ganglioneuroma of Glossopharyngeal Nerve in a Patient with Glossopharyngeal Neuralgia: A Case Report

“…6,7) GPN due to a CPA neoplasm (such as epidermoid) has been previously reported; however, it is very rare and usually occurs due to compression on glossopharyngeal nerve by a large cerebello-pontine tumor. 2,6,8) Our case is the first case of GPN completely resolved after removal ganglioneuroma with glossopharyngeal neurectomy as well as micro-vascular decompression (MVD) to decompress the glossopharyngeal nerve roots with vagal nerve roots. Here, we think ganglioneuroma was just incidental development of tumor in the patient with pre-existing neuralgia and it might worsened the neuralgic sufferings of the patient.…”

“…However, GPNs can also be caused by compression of a nerve by a mass lesion. There is several reports where tumors are associated GPN 1 , 2 , 3 , 6) where ix nerve is compressed by extrinsic large size tumor in cerebello-pontine angle (CPA) but till today, there is no report of glossopharyngeal nerve ganglioneuroma or ganglioneuroma of ix nerve with pre-existing GPN. Here, we report a case of very small glossopharyngeal nerve ganglioneuroma near jugular foramen (JF) and the patient also had longstanding GPN.…”

“…Ganglioneuroma is a neural crest origin tumor commonly occurs in mediastinum, adrenal glands, and peripheral nervous system but very rarely it occur in cranial cavity. [1][2][3] Very few cases of intracranial ganglioneuroma arising from the trigeminal nerve have been reported in the literature. 2,3) Glossopharyngeal neuralgia (GPN) is a rare clinical condition characterized by intense lancinating pain in throat commonly triggered by swallowing 4) but also by talking, chewing, yawning, and laughing.…”

The pain is severe and paroxysmal; it originates in the throat, approximately in the tonsilar fossa.…”

Spontaneous Intracystic Hemorrhage in an Adult with Cerebellopontine Angle Arachnoid Cyst and Management: A Case Report

“…Most typically, CPA arachnoid cysts are incidental findings in asymptomatic patients and can be safely monitored with serial imaging. Patients with symptomatic CPA AC can present with a variety of symptoms due to brainstem or cranial nerve compression [2] including sensorineural hearing loss [4,5] diplopia [6], trigeminal neuralgia [7], vertigo [8], hemifacial spasm [9], facial paresis [10], glossopharyngeal neuralgia [11], hoarseness and dysphagia [12]. Jallo, et al reviewed 33 cases of CPA AC and discussed optimal surgical management.…”
