Ictal extension (dorsiflexion) of the toes in a patient with temporal lobe epilepsy: A new ictal lateralizing sign
چکیده انگلیسی

Neurologists have analyzed the clinical behaviors that occur during seizures for many years. Several ictal behaviors have been defined in temporal lobe epilepsy (TLE). Ictal behaviors are especially important in the evaluation of candidates for epilepsy surgery. We propose a new ictal lateralizing sign originating from the nondominant hemisphere: extension (dorsiflexion) of the toes (Babinski's, Chaddock's, and Moniz’ signs). Our patient is a 16-year-old woman. Her epileptogenic foci were localized to the right neocortical temporal region after noninvasive presurgical investigations. Cranial MRI revealed a right insular lesion compatible with focal cortical dysplasia or cortical tumor. We observed progressive movement of the left leg and, when the patient touched the lateral aspect of the foot to the bed, dorsiflexion of the great toe (Babinski's sign). In other seizures, the patient started a progressive movement of the left leg, rubbing the external border of the left foot on the bed and provoking dorsiflexion of the great toe (Chaddock's sign). The Brissaud reflex component was also observed when the movement was accompanied by internal rotation of the leg and recruitment of the tensor fascia lata, making dorsiflexion more likely to be a reflex response and not voluntary. We also observed forceful passive plantar flexion at the ankle in association with dorsiflexion of the great toe (Moniz’ sign). All of these signs were contralateral to ictal seizure onset and to the cerebral epileptogenic lesion. These signs may occur as a result of ictal activation of a specific brain region in this hemisphere.
