Abstract

Ictal semiology is essential to identify the epileptogenic zone (EZ), especially in drug-resistant focal epilepsy (DRE), as its accurate identification determines the surgical prognosis. Dancing is highly unusual ictal semiology, and its underlying neural networks remain somehow unclear since both temporal and frontal lobe (FL) have been implicated in its generation. We present a 21-year-old male with DRE characterized by dancing seizures. Homemade videos were obtained. Through a non-invasive pre-surgical evaluation, the epileptogenic zone was localized within a gross lesion in the left FL. Using stereo electroencephalography (SEEG), we successfully identified the ictal-onset zone in the mesial middle, inferior, and orbito-frontal cortex, with rapid propagation of ictal activity extending backward and laterally to the precentral regions. Subsequently, a left frontal middle and inferior gyrectomy was performed, resulting in seizure freedom for the patient. Pathology results revealed a mild malformation of cortical development with oligodendroglial hyperplasia (MOGHE). Atypical seizure semiology, such as dancing, provides an interesting starting point for the analysis of the areas involved in the EZ. Further intracranial recordings are required to fully comprehend the underlying networks and interactions of cerebral areas during dancing seizures.

Keywords: frontal seizures; ictal dancing; neural networks.
