Purpose: Palinacousis is an auditory illusion of sound persisting or repeating after the cessation of an auditory stimulation. Up until now, approximately 32 cases have been reported. The purpose of this study is to describe an additional seven cases of palinacousis and review our understanding of audition and palinacousis.

Methods: Patients seen in the epilepsy clinic or admitted to the Epilepsy Monitoring Unit (EMU) at The Mount Sinai Hospital who experienced palinacousis were included. In all these patients, an EEG and MRI were performed at some point during their clinical course.

Results: In one case, palinacousis occurred with stimulation of the superior temporal gyrus during brain mapping after a spoken word as well as after the thought of a word. Two people experienced palinacousis during a seizure captured on video EEG. The remaining four cases had palinacousis in the peri- or post-ictal period.

Conclusions: We propose that palinacousis may be coming from the superior temporal gyrus secondary to seizure activity, either onset or spread, or dysfunction of the area in a postictal state. The existence of palinacousis in these pathologic states can help us to understand how we process auditory information.
