Multiple etiological factors have been associated with infantile spasms (IS), and are usually linked to diffuse or multifocal brain damage. It is generally believed that infants with symptomatic IS have a significantly higher incidence of mental retardation and epilepsy than those with cryptogenic IS. However, IS secondary to focal brain lesions in which surgical removal of the lesions has resulted in cessation of generalized spasms and subsequent normal development are rarely reported. A seven-month-old male infant who manifested head nodding and generalized flexor spasms one month prior to the admission is reported. Waking interictal electroencephalography revealed a pattern of burst-suppression variant of hypsarrhythmia. Brain magnetic resonance imaging disclosed a huge porencephalic cyst over the left temporo-parietal region. The infant underwent craniotomy with corpus callosotomy, causing marked improvement in seizures. He attained subsequent stable psychomotor development.
