Abstract

Limbic encephalitis involving anti-voltage-gated potassium channel antibodies (VGKC-LE) has become increasingly recognised, with seizures and psychotic features, such as hallucinations, being typical clinical manifestations. Though the literature supports auditory hallucinations as ictal phenomena, there are no reported cases of these hallucinations correlating with electrographic seizure for this disease entity. Early recognition of auditory hallucinations as seizures could alter treatment and subsequently affect short-term outcomes in these patients. We report the case of a patient with auditory hallucinations and progressive cognitive decline, as well as serological evidence of VGKC antibodies, in whom ictal hallucinations were identified by continuous video-EEG monitoring. This case highlights the subtlety of this entity, in both clinical and electrographic detection.
