| Abstract: | A cerebellopontine angle tumor cannot be reliably diagnosed from a classical clinicotopographic cerebellopontine angle syndrome. There is also a vascular cerebellopontine angle syndrome which is not too rare an occurrence. In some cases of tumorigenesis, where there is no papilledema and no characteristic increase in total liqour protein, it is not possible to make a clear decision between tumorous growth and vascular syndrome. The extension of the internal auditory meatus cannot be considered to be a symptom clearly indicating the presence of a tumor. |
