Congenital Bilateral Perislyvian Syndrome: Case Report and Review of Literature

Congenital bilateral Perislyvian syndrome (CBPS) is a rare structural malformation of the brain in which the underlying anomaly is polymicrogyria. Polymicrogyria is a malformation of cortical development that is characterized by abnormal arrangement and excessive folding of cerebral cortical cell layers, often with fusion of the gyral surfaces, which can be focal or regional or involve the whole cortical mantle. Clinical manifestations depend upon the anatomical region of the brain involved. We report a case of 7-year-old male child with magnetic resonance imaging findings of CBPS.
