Sudden bilateral hearing loss is mainly caused by peripheral otologic disorders or psychogenic origins. Bilateral temporal lobe infarcts can be one of the rare causes. We report a 50-year-old man presented with cortical deafness due to bilateral temporal lobe infarctions. He was admitted at hospital because he did not respond to any verbal questions or environmental sounds, although he understood written commands partially and spoke fluently. Brain MRI demonstrated ischemic infarcts in both temporal lobes involving primary auditory cortex.
