At the time of diagnosis, about 20% of patients with gastric cancer have stage IV disease involving the liver, lung, and bone. Brain metastasis from gastric cancer is exceedingly rare, with an incidence of <1% of clinical cases. A 59-year-old man was admitted with hearing loss in the left ear and left facial palsy for 1 month. A magnetic resonance imaging scan revealed a tumor in the cerebellop...

OBJECTIVES To determine the sensitivity of auditory brainstem response (ABR) testing for detecting acoustic neuromas and to determine whether the test is less sensitive for detecting small tumors. DESIGN Retrospective review of the medical charts of 58 patients with acoustic neuroma who had all of the data necessary for inclusion in the study. SETTING University-affiliated referral practice...

Sporadic vestibular schwannoma (acoustic neuroma) is a benign tumor arising from cochleovestibular nerve. Nowadays, various specialties and medical centers are treating this disease, and the multidisciplinary collaboration is the trend. In an effort to promote a uniform standard for reporting clinical results, even for treatment indications, the mainly controversies were posed and discussed dur...

it has been shown recently that loud clicks evoke myogenic potentials in the tonically contracting sternocleidomastoid muscles. studies have suggested that these potentials are of vestibular origin, especially of the saccule and inferior vestibular nerve. a pilot study was undertaken in our hospital to record vestibular evoked myogenic potentials (vemp) for the first time in iran. eighteen heal...

Here we present the pooled analysis of 2 case-control studies on the association of brain tumours with mobile phone use. Use of analogue cellular phones increased the risk for acoustic neuroma by 5%, 95% confidence interval (CI) = 2-9% per 100 hrs of use. The risk increased for astrocytoma grade III-IV with latency period with highest estimates using >10-year time period from first use of these...
