title: Clinics in diagnostic imaging.
abstract: A 48-year-old Chinese woman presented with progressive right-sided sensorineural hearing loss. Computerised tomography showed asymmetrical widening of the right internal acoustic canal. Post-gadolinium magnetic resonance images demonstrated marked enhancement of an intracanalicular tumour. The diagnosis of acoustic neuroma was confirmed surgically. The approach to imaging of deafness, particularly of unilateral sensorineural hearing loss, is discussed. Magnetic resonance imaging is currently the definitive test for diagnosis of acoustic neuromas.
