account for account for 8% of all primary brain tumours in adults, with most cases being acoustic neuromas, intraparenchymal schwannomas of the brain are rare. Gibson et al. (1) reported the first English-language account of an intraparenchymal intracerebral schwannoma in 1966. Since then, several other cases of this neoplasm have been reported (2, 3). We present a case of an unusual intracrani...

The repetition and the predictability of a word in a conversation are two factors that are believed to affect whether it is emphasized: predictable, repeated words are less acoustically prominent than unpredictable, new words. However, because predictability and repetition are correlated, it is unclear whether speakers lengthen unpredictable words to facilitate comprehension or whether this len...

The purpose of this study was to establish the frequency and pattern of depressive disorders after surgery for acoustic neuroma, and to look for associations. Twenty seven patients with acoustic neuroma underwent thorough psychiatric assessment before surgery and at three and 12 months after surgery. Three patients had a depressive disorder in the preoperative assessment. Of the remaining 24 pa...

Our case-control studies were the first to report an association between the use of mobile or cordless phones and brain tumors; glioma and acoustic neuroma. Criticism of these results has been based partly on results from the Interphone studies conducted under the auspice of the International Agency for Research on Cancer (IARC). Here, we compare study design and epidemiological methods used in...

Experience with 81 gas computed tomography (CT) cisternography procedures in 79 patients in searching for acoustic neuroma is reported. Twenty-one tumors, four exclusively intracanalicular, were demonstrated after standard contrast-enhanced CT was negative. Fifty-five examinations were negative; four were inconclusive. The high resolution scanner with digital localization and reconstruction zoo...
