Secreted Factors from Human Vestibular Schwannomas Can Cause Cochlear Damage
Vestibular schwannomas (VSs) are the most common tumours of the cerebellopontine angle. Ninety-five percent of people with VS present with sensorineural hearing loss (SNHL); the mechanism of this SNHL is currently unknown. To establish the first model to study the role of VS-secreted factors in causing SNHL, murine cochlear explant cultures were treated with human tumour secretions from thirtee...
متن کاملExtracellular vesicles derived from human vestibular schwannomas associated with poor hearing damage cochlear cells.
BACKGROUND Vestibular schwannoma (VS) is a tumor of the vestibular nerve that transmits balance information from the inner ear to the brain. Sensorineural hearing loss occurs in 95% of patients with these tumors, but the cause of this loss is not well understood. We posit a role of VS-secreted extracellular vesicles (EVs) as a major contributing factor in cochlear nerve damage. METHODS Using ...
متن کاملMajor nerve schwannomas vs intramuscular schwannomas
Background: A schwannoma is a benign peripheral nerve tumor. Predicting the involvement of a nerve on symptoms or MR findings is crucial to the diagnostic process. Purpose: To compare symptoms, MR findings, and histological findings between major nerve schwannomas and intramuscular schwannomas. Material and Methods: Thirty-four patients with 36 schwannomas (29 major nerve schwannomas and 7 intr...
متن کاملRetroperitoneal schwannomas
BACKGROUND Retroperitoneal schwannomas are very rare and are usually found incidentally. CASES REPORT Two rare cases of retroperitoneal schwannomas are reported. Both were incidentally found during US scans for non-specific epigastric pain and were initially diagnosed as non-secreting retroperitoneal tumors. The diagnosis was confirmed by CT scan. In both patients the tumors were resected. Th...
متن کاملMobile cauda equina schwannomas
Although very rare, cases of cauda equina tumours migrating several levels have been known to occur. We report two cases of cauda equina schwannomas which migrated from its primary site, one caudally and the other one rostrally as confirmed by magnetic resonance imaging perioperatively. The f irst patient was a 27-year-old man and the second a 41year-old man; both presented with back pain. This...
