Abstract:
Stroke results in sudden loss of function related to its damaged portion. When this occurs in temporal lobe, the function of hearing and listening may be affected, although receptive language processing is affected while hearing perception is relatively spared. This is called as “central deafness.” It has been known that hearing ability is seldom impaired in the case of temporal lobe stroke except in the case of bilateral lesions. However, we experienced a 72-year-old, right-handed woman who presented with both sudden hearing difficulty due to unilateral temporal lobe infarctions after suddenly not being able to respond to any verbal questions except environmental sounds. Pure-tone audiometry showed both flat sensorineural hearing loss of mild degree in both ears but she could not understand any verbal sound. Brain MRI demonstrated extensive ischemic infarcts in the left temporal lobes involving primary auditory cortex. She was diagnosed as verbal auditory agnosia and has received speech-language therapy.
