AIM OF THE STUDY Efficacy of stereotactic radiosurgery (SRS) in the treatment in cerebral AVM's, mennigiomas, metastases, acoustic neuromas and recurrent anaplastic gliomas is well documented. The object of this work was the analysis of the results of the treatment of AVM and selected cerebral lesions with linear accelerator-based stereotactic radiosurgery. MATERIAL AND METHODS THE LESIONS IN...

OBJECTIVE To determine whether unilateral activation of the vestibular labyrinth by brief air conducted tones can elicit disconjugate reflex eye movements in healthy subjects. METHODS 40 normal volunteers, one patient with bilateral congenital sensorineural deafness, and four patients with an acoustic neuromas were subjected to monoaural air conducted tones (125 to 6000 Hz; 132 dB SPL; 3-4 ms...

Objective To describe the change in the management of acoustic neuromas at one United Kingdom center over a 20-year period and to compare this with what is known regarding trends in practice on a national and international scale. Design, Setting, and Participants Data was collected prospectively on all patients attending the Oxford Skull Base Clinic between 1990 and 2009. Main Outcome Measures ...

PURPOSE To assess the value of MR in patients with sensorineural hearing loss (SNHL) caused by lesions other than acoustic neuromas. METHODS MR studies of 51 patients with SNHL were retrospectively reviewed; patients with acoustic neuroma were excluded to focus on the more uncommon causes. RESULTS Twenty patients had labyrinthine lesions. Six patients had viral labyrinthitis, one patient ha...

Protocols and results of case-control studies, pooledand meta-analyses on the relationship between mobile phone use and risk of head tumours are critically analysed, and for each study strict elements necessary for evaluating its reliability are identified and applied (see Methods). In studies funded by public bodies, blind protocols give positive results revealing cause-effect relationships be...

Two sisters, ages 37 and 26 years, developed bilateral acoustic neuromas and multiple intracranial meningiomas. Their mother and two other siblings also had bilateral acoustic neuromas. During a routine MR study of the brain of the older sister, an abnormality (possibly a mass) was found at the cervical medullary junction. This patient had no symptoms referable to this area, and postoperative c...

Acoustic neuromas (AN) are schwann cell-derived tumors that commonly arise from the vestibular portion of the eighth cranial nerve also known as vestibular schwannoma(VS) causes unilateral hearing loss, tinnitus, vertigo and unsteadiness. In many cases, the tumor size may remain unchanged for many years following diagnosis, which is typically made by MRI. In the majority of cases the tumor is s...
