Abstract
A case report of an 11 year old boy with new onset of a seizure disorder is presented.
A computed tomography scan demonstrated a noncalcified, nonenhancing focal region
of abnormal cortex. A magnetic resonance imaging scan delineated both an isointense
area of abnormally thickened gyri and linear areas of abnormal high signal intensity
in the subjacent white matter. A review of the radiologic and pathologic literature
suggests that this lesion represents the entity focal cortical dysplasia as described
by Taylor, et al. This abnormality is part of a spectrum of disorders including hamartomas
(of tuberous sclerosis), focal cortical dysplasia and heterotopias.
