چکیده انگلیسی
We describe two cases of refractory epilepsy with cerebral hemiatrophy and contralateral electroencephalographic (EEG) abnormalities, in which hemispherotomy of the atrophic hemisphere effectively controlled seizures. Case 1 was a 5-year-1-month-old girl with refractory bilateral asymmetrical tonic posturing seizures predominantly in the right arm. Magnetic resonance imaging showed left porencephaly corresponding to a left middle cerebral artery infarction. Case 2 was a 3-year-8-month-old boy with refractory bilateral asymmetrical tonic posturing seizures predominantly in the right arm due to atrophy of the left cerebral hemisphere after septic meningitis. Both patients had right hemiparesis and was incapable of pinching by the right hand. Contralateral interictal and ictal EEG abnormalities were observed. Interictal 99mTc-ethyl cysteinate dimer (99mTc-ECD) single photon emission computed tomography (SPECT) showed hypoperfusion and ictal 99mTc-ECD-SPECT showed hyperperfusion within the left cerebral hemisphere. Left hemispherotomy was performed. Cases 1 and 2 remained seizure-free at the last follow-up 18â¯months and 15â¯months, respectively, after surgery, and contralateral interictal EEG abnormalities disappeared. In patients with cerebral hemiatrophy and contralateral EEG abnormalities, epilepsy surgery may be considered when the laterality of seizure semiology, functional imaging findings and motor deficits were concordant with the atrophic side. Ictal SPECT is effective to confirm the epileptogenic hemisphere.
