AIM: We investigated the clinical presentation and management issues of unilateral vestibular schwannomas in childhood without evidence of neurofibromatosis. MATERIAL AND METHODS: Ten pediatric patients with unilateral vestibular schwannomas and no evidence of neurofibromatosis were treated by the senior author at Tiantan Hospital from January 1994 to December 2014. The clinical manifestations, neuroimaging findings, treatment methods, and therapeutic results were retrospectively reviewed...

Demyelinating lesions were recognized as a kind of rare central nervous system demyelinating lesion. The diagnosis and differential diagnosis of demyelinating lesions is difficult. Once the diagnosis was delayed or incorrect, it will make a great impact on patients.Demyelinating lesions often involved in young and middle-aged, but this patient was the aged, which is rare.

Surgical approaches to vestibular schwannomas (VS) are widely known and extensively recorded. For the first time, an exclusive endoscopic approach to the internal acoustic canal (IAC) was described and used to safely remove a cochlear schwannoma involving IAC in March 2012. The aim of this article was to summarize indications and technique to treat intracanalicular VS by transcanal/transpromontorial endoscopic approach. Because management of intracanalicular VSs is complex and strongly debated, this kind of therapeutic option in the appropriate and selected cases could modify classic concepts of the management of this pathology...

In the central nervous system, cerebellopontine angle (CPA) lymphomas are rare; few cases have been reported. Lymphoplasmacytic lymphoma (LPL) in the CPA is rarer still, and often misdiagnosed as acoustic neuroma.We report a rare case of CPA LPL-a challenging diagnosis guided by clinical presentations, radiological signs, and postoperative pathological test.A 43-year-old woman presented with headaches. Her magnetic resonance imaging revealed an abnormal homogeneously enhancing mass in the left CPA. We present detailed analysis of her disease and review relevant literature...

The Gamma Knife Check software is an FDA approved second check system for dose calculations in Gamma Knife radiosurgery. The purpose of this study was to evaluate the accuracy and the stability of the commercial software package as a tool for independent dose verification. The Gamma Knife Check software version 8.4 was commissioned for a Leksell Gamma Knife Perfexion and a 4C unit at the University of Pittsburgh Medical Center in May 2012. Independent dose verifications were performed using this software for 319 radiosurgery cases on the Perfexion and 283 radiosurgery cases on the 4C units...

Acoustic neuroma resection is an example of a neurosurgical procedure where the brainstem and multiple cranial nerves are at risk for injury. Electrode placement for monitoring of the glossopharyngeal and hypoglossal nerves during acoustic neuroma resection can be challenging. The purpose of this report is to illustrate the use of a device for intra-oral electrode placement for intraoperative monitoring of the glossopharyngeal and hypoglossal nerves. A 60-year-old male presented for acoustic neuroma resection...

It has been over 200 years since the acoustic neuroma(AN) was firstly reported. From simply describing its symptoms to the decline of surgical mortality, the protection of facial and acoustic nerve function, as well as the improvement of the patients' quality of life. Physicians made efforts on evolving the diagnostic techniques and treatment strategies, and a better understanding of AN's development. The current major managements of AN are microsurgery, stereotactic radiosurgery, and follow-up. We reviewed the AN's history and prospected its future managements...

OBJECTIVE: To describe and analyze the strategy of the diagnosis and treatment for acoustic neuroma associated with hydrocephalus. METHODS: A retrospective review was performed in 29 patients with hydrocephalus associated with acoustic neuroma form Apr. 2004 to Apr. 2015. The patients' clinical information, the types of the hydrocephalus, the treatment and the prognosis of the hydrocephalus were recorded. RESULTS: There were 20 patients with obstructive hydrocephalus and 9 patients with communicating hydrocephalus preoperatively...

OBJECTIVE: To investigate the relationship between the amplitude change of supramaximal facial nerve stimulation during acoustic neuroma removal and facial function outcome, and discuss its influencing factors. METHODS: Retrospective study of 34 acoustic neuroma patients. Intraoperative amplitude by supramaximal stimulation, facial function outcome, tumor size, surgical approach, facial nerve course pattern, and tumor cystic status, as well as tumor adhesion degree were collected and analyzed by SPSS 17...

OBJECTIVE: To discuss the method as well as effect of hearing restoration for patients with acoustic neuroma (AN) in the only hearing ear. METHODS: A retrospective study was conducted in three patients with AN in the only hearing ear. Ipsilateral cochlear implantation (CI) was performed in case 1 and contralateral CI was performed in case 2 without tumor resection. In case 3, CI was performed 6 months after tumor removal by the retrosigmoid approach. Dynamic changes in the audiological tests was recorded regularly...

OBJECTIVE: To evaluate the efficiency of the descending hypoglossal branch-facial nerve anastomosis for the severe facial palsy after acoustic neuroma resection. METHODS: The clinical data of 14 patients (6 males, 8 females, average age 45. 6 years old) underwent descending hypoglossal branch-facial nerve anastomosis for treatment of unilateral facial palsy was analyzed retrospectively. All patients previously had undergone resection of a large acoustic neuroma...

BACKGROUND: The management of vestibular schwannoma is still a quite controversial issue and can include wait and see policy, surgery and radiotherapy, mainly with stereotactic technique. The purpose of this study is to review the results of recent clinical series treated by radiotherapy. MATERIALS AND METHODS: Literature search was performed by Pubmed and Scopus by using the words "vestibular schwannoma, acoustic neuroma, radiotherapy, radiosurgery". RESULTS: Management options of VS include wait and see, surgery and radiotherapy...

AIM: Surgery for acoustic neuroma has developed over the years with a gradual improvement in outcome. The goal of surgery should be cure of the disease and a low morbidity, preserving facial nerve function - and hearing, too, whenever feasible (i.e. in small tumors). The most appropriate approach must be decided case by case. BACKGROUND: Results of microsurgery remain heterogeneous, however, probably due to the different amount of experience gained at different centers...

BACKGROUND: The aim was to investigate associations between different measures of socioeconomic position (SEP) and incidence of brain tumours (glioma, meningioma and acoustic neuroma) in a nationwide population-based cohort. METHODS: We included 4 305 265 individuals born in Sweden during 1911-1961, and residing in Sweden in 1991. Cohort members were followed from 1993 to 2010 for a first primary diagnosis of brain tumour identified from the National Cancer Register...

UNLABELLED: GENERAL: Treatment of vestibular schwannoma (VS) via microsurgery, radiosurgery (SRS), or fractionated radiotherapy (FRT), is advocated for symptomatic patients or those with rapid tumor growth, despite older age and comorbidities. VS growth rate >2.5 mm/year is associated with lower hearing preservation rates. Regardless of growth rate, conservative management is associated with a progressive hearing loss, ranging 2.77-5.39 dB/year. MICROSURGERY: The retrosigmoid approach is associated with higher hearing preservation and facial nerve function rates for VS >1...
