[Diagnosis of cerebello-pontine angle tumors]

History and results of investigations in 34 patients with cerebello-pontine angle tumours are presented. Tumour was diagnosed in the first, audiological stage of the disease only in 4 patients. In 7 more patients additional symptoms of central nervous system focal disorders occurred. The remaining 23 patients were in the third stage of the disease with symptoms of increased intracranial pressure. The main reason for such a late diagnosis of the tumour was neglecting of the early audiological symptoms of the disease by patients and by general practitioners as well.
