<jats:bold>Introduction</jats:bold>
: Double hearing or Diplacusis is a synchronous double perception of a sound and can have Binauralis or Monauralis pattern, with inner ear disorders being the main culprit

. Other forms of Auditory illusions have been reported as a co‐manifestation of stroke syndromes, but none as an isolated presentation
<jats:sup>[1][2]</jats:sup>
. This is a case of a 77‐year‐old male with acute onset isolated Diplacusis in a patient due to a right temporal lobe ischemic infarct. To our knowledge, this is the first case report of an isolated diplacusis due to cortical infarct.

: The patient had a past medical history of sensorineural deafness in his left ear. He described any sound heard as the same quality but occurring with an echo heard a fraction of a second later in his right ear. There was no decreased hearing quality or tinnitus reported in his right ear. His drug screen test was negative. His examination was only remarkable for a sensorineural hearing loss pattern on his left ear. His (NIHSS) was zero, and no other cranial nerve abnormalities were detected. His MRI was significant for a punctate restricted diffusion on the right temporal lobe, resembling an ischemic infarct (Figure).

<jats:bold>Conclusions</jats:bold>
: Isolated diplacusis can present as acute ischemic stroke in the temporal lobe. Further studies are needed to understand its pathophysiology.
