Tumor7
  • In rare cases, a facial nerve neuroma, vascular tumor, lipoma, or metastatic lesion is found within the cerebellopontine angle. (medscape.com)
  • Differential considerations for the unusual location of this rare tumor are discussed. (elsevierpure.com)
  • Glomus tympanicum tumors are a rare type of middle ear tumor that often present with symptoms such as pulsatile tinnitus, hearing loss, and ear fullness. (jcohns.org)
  • However, for the part of the brain where they are located, called the cerebellopontine angle, it is the most common tumor type. (florenceent.com)
  • Liponeurocytoma is a rare grade II glioneuronal tumor of the central nervous system that mostly occurs in middle-aged adults and is located in the cerebellar hemisphere. (ruralneuropractice.com)
  • Schwannomas of the jugular foramen, usually with origin from the ninth nerve, are rare, but the presenting symptoms may be similar to those of a vestibular schwannoma owing to mass effect by tumor growth in the posterior cranial fossa (2-4) . (ajnr.org)
  • Secondary trigeminal neuralgia (STN): caused by a major underlying neurological disease, most frequently multiple sclerosis , a tumor at the cerebellopontine angle , or arteriovenous malformation . (amboss.com)

Lesion2
  • Choroid plexus papilloma, also known as papilloma of the choroid plexus, is a rare benign neuroepithelial intraventricular WHO grade I lesion found in the choroid plexus. (wikipedia.org)
  • The latter revealed a tension hydrocephalus and an infarction lesion in the right cerebellopontine angle. (hippokratia.gr)
Auditory1
  • The 4 nerves in question (2 vestibular, cochlear and facial) run through a small bony canal (internal auditory canal) for about 1 cm before entering in the cerebellopontine angle and reaching the entry zone in the brain stem, part of the brain where originate the majority of cranial nerves. (microneurosurgery-roma.com)
Cerebellar1
  • [ 1 ] Multifocal cerebellar liponeurocytoma is extremely rare and their management is still the subject of controversy. (ruralneuropractice.com)
Spinal1
  • No significant postoperative changes in the paraspinal Goutallier grade or spinal angles were observed. (thejns.org)
Vestibular2
  • Here we presented a rare case of acute vestibular neuritis after the adenoviral vector-based COVID-19 vaccination. (springer.com)
  • Vestibular schwannomas are benign tumors of the cerebellopontine angle that can cause hearing loss, tinnitus, and vertigo. (jcohns.org)

Tinnitus1
Diameter1
Facial1
  • A rare phenomenon, facial baroparesis is thought to result from ischemic neuropraxia of CN VII as it passes through the tympanic segment of the facial (Fallopian) canal. (biomedcentral.com)
Acute1
  • The acute origin angle of the vessel from the basilar artery made both malformations unsuitable for endovascular treatment. (surgicalneurologyint.com)
Genetic1
  • These are individuals with a rare genetic disorder called neurofibromatosis type 2 (NF2), which accounts for 5% of all cases of acoustic neuromas. (facialparalysisinstitute.com)
Relatively rare2
  • Forms of segmental or peripheral myoclonus are relatively rare. (msdmanuals.com)
  • The tumors are most commonly located in convexities, and it is relatively rare to find such a growth in the parietal region such as the one presented in this case report. (wanderluce.com)
Typically1
  • It is a rare condition that typically manifests in patients above the age of 60 years and affects women more often than men. (amboss.com)
Brain2
  • The tumors are rare, accounting for only five to seven percent of all brain tumors. (florenceent.com)
  • In Neurosurgical Departments with medium-high experience, the acoustic neuromas surgical mortality is close to zero, and in those rare cases when it happens, there are usually huge neuromas, very adherent to the brain stem and/or with hydrocephalus. (microneurosurgery-roma.com)
Acoustic2
Peripheral1
  • Hepatosplenic T cell lymphoma (HSTCL) is a very rare and aggressive peripheral T cell lymphoma that comprises less than 1% of Non-Hodgkin lymphomas. (plexa.ai)
Commonly1
  • It is a rare condition, most commonly reported in barotraumatic environments, in particular scuba diving and high-altitude air travel. (biomedcentral.com)
Treatment1
  • Education regarding this rare condition may prevent unnecessary testing and treatment of affected patients. (biomedcentral.com)
Origin1
Present1

Condition1
  • Familial clustering is rare for this condition ( 4 ). (aerzteblatt.de)
Middle1
  • Bacterial forms are rare and can result from an untreated middle ear infection or meningitis. (springer.com)
