Temporal neocortical origin of pilomotor seizures in association with an infiltrating glioma: a case confirmed by intracranial electroencephalography monitoring

Abstract

Patients with seizures occasionally present with autonomic symptoms. Pilomotor seizures are uncommon and usually accompanied by other manifestations of complex partial seizures of limbic origin. Activation of the central autonomic network appears to be necessary for the development of ictal goose bumps. Pilomotor seizures have been reported to originate in the temporal lobe and other medial limbic structures. Ictal piloerection can arise due to a variety of brain pathologies. Isolated pilomotor seizures are very rare. The authors present the first case in which intracranial electroencephalography monitoring was used to confirm pilomotor seizures of temporal neocortical origin in association with an infiltrating tumor.
