Acoustic Neurinomas
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...

متن کاملAsymmetric optokinetic afterresponse in patients with small acoustic neurinomas.
Directional asymmetry of primary and secondary optokinetic afternystagmus (OKAN I and OKAN II, respectively) was studied in 20 patients with small acoustic neurinomas (< or = 20 mm), and results were compared to those for 24 normal controls. The optokinetic afterresponse was induced by 60 s of horizontal whole-field optokinetic stimulation in both directions. Among patients, the optokinetic aft...
متن کاملSystematic evaluation of Stereotatic Radiosurgery effects in metastasis and acoustic neurinomas using MRI
INTRODUCTION: Stereotactic radiosurgery (SRS) is a specific form of radiation therapy used to treat tumors and other abnormalities in the brain. This technique uses a few highly focused X-rays beams usually delivered in a single high-dose. To maximize the radiation dose in the tumor, and to minimize the damage in collateral healthy areas, the treatment uses a frame-like device that keeps the he...
