title: ABR latency-intensity function abnormality in the early detection of a cerebellopontine angle tumour: a case study.
abstract: A case is presented of a 27-year-old male subject with a cerebellopontine angle tumour which was provisionally diagnosed on the basis of the ABR latency-intensity function findings and later confirmed by MRI. The patient initially presented with decreased hearing sensitivity, tinnitus and dizziness. The findings of neuroaudiological assessments and radiological examinations are described. The importance of the neuroaudiological test battery, in particular the ABR latency-intensity function, in this case is discussed; and the need for its inclusion for earlier detection and diagnosis of cerebellopontine angle tumours emphasized.
