Pilomotor seizures: a video case report.

Piloerection is a rare ictal manifestation usually associated with temporal lobe epilepsy. We present video and electrographic documentation of pilomotor seizures in a 75-year-old man with left temporal lobe epilepsy and remote herpes zoster encephalitis. In general, piloerection is most often localised to the temporal lobe. Unilateral piloerection is usually associated with an ipsilateral ictal onset. Bilateral piloerection has a less certain lateralising value, although earlier reports suggest left hemispheric predominance [Published with videosequences].
