Focal Cortical Dysplasia: A Pictorial Review

Abstract

Abnormalities of cortical development are frequent causes of refractory epilepsy. Among these pathologies, focal cortical dysplasia (FCD) is a heterogeneous group of disorders pathologically characterized by loss of normal cortical structure. Two distinct entities with different etiology have been described (FCD type I and FCD type II Taylor). This study presents relevant case studies, highlighting the pathological features in magnetic resonance imaging.
