title: Porencephaly: computed tomography (CT) scan findings.
abstract: Twenty-six cases of porencephalic cysts were analyzed. The cysts were multiple in 26.9% and were associated with subarachnoid cysts in 11.5%. The main presentations were seizures, cerebral palsy and mental retardation. The unifocal cysts were mainly in the frontoparietal region, suggesting a congenital aetiology. Multiple cysts were noted in the basal ganglia region. A case of multiloculated cysts, of unknown aetiology, is noted. The aetiology of multifocal porencephaly and a diagnostic method of differentiating congenital from acquired porencephaly are discussed.
