Seizure-induced miosis
Seizure-induced miosis
Ictal autonomic pupillary dilation is common; however, miosis is rare. We describe a case of focal seizures secondary to cortical dysplasia presenting with bilateral pupillary miosis, rendered seizure free by resective surgery. The seizure-onset zone was localized within the left middle parietal gyrus by intracranial electrographic recording. Seizure onset was coincident with focal left centroparietal fast spike activity on electroencephalography (EEG). A large region of the left frontocentral cortical dysplasia was demonstrated on magnetic resonance imaging (MRI). Complete resection of the area of cortical dysplasia and additional cortical regions of ictal activity, identified using intracranial EEG, rendered the patient seizure free.

Abstract
Ictal autonomic pupillary dilation is common; however, miosis is rare. We describe a case of focal seizures secondary to cortical dysplasia presenting with bilateral pupillary miosis, rendered seizure free by resective surgery. The seizure-onset zone was localized within the left middle parietal gyrus by intracranial electrographic recording. Seizure onset was coincident with focal left centroparietal fast spike activity on electroencephalography (EEG). A large region of the left frontocentral cortical dysplasia was demonstrated on magnetic resonance imaging (MRI). Complete resection of the area of cortical dysplasia and additional cortical regions of ictal activity, identified using intracranial EEG, rendered the patient seizure free.
