Acoustic neuroma [Neurilemmoma, Schwannoma] accounts for 8% of all intracranial tumours and about 80% of those occurring in the cerebellopontine angle [C. P. A.] . The tumour is usually solitary but may occur bilaterally in cases of familial neurofibromatosis [von Reck-linghausen ‘s Disease] . Symptoms and signs of acoustic neuroma are greatly dependent on the size of the tumour. Early diagnosis is difficult in many cases either because there is lack of symptoms or manifestations of non-specific symptoms. Availability of new diagnostic tests [electrophysiological and neuro-radiological] has allowed early detection of small acoustic neuromas, optimizing surgical results and reducing patient morbidity. Most important role in early diagnosis still remains with the clinicians who must perform screening tests for acoustic tumour suspects. Unilateral hearing loss, tinnitus and unsteadiness are the cardinal symptoms of acoustic tumour. Modern audiometry with acoustic reflex testing, brainstem evoked responses and computed tomography have played considerable role in early diagnosis of acoustic neuroma
