Abstract:
Pure word deafness refers to an inability to understand spoken language with relatively normal reading, writing and speaking as well as comprehension of nonverbal sounds. We report a case of 36 year-old right-handed man with a mitral valve prolapse who presented with a pure word deafness following bilateral primary auditory cortical infarction. The auditory deficit was specific for spoken language, while recognition of non-verbal sounds was normal. Pure tone threshold audiometry revealed mild sensorineural loss up to 2000 Hz and a moderate high frequency loss. Brainstem auditory evoked potentials were normal. Brain MRI showed that the infarction was confined to bilateral superior temporal gyri including primary auditory cortex.
