Absence of the corpus callosum (ACC) represents a complex malformation of neural development, which may occur in isolation or in combination with other cerebral anomalies (Barkovich, 1991). Most cases are sporadic but familial forms do exist. Abnormalities in the limbic formations and the anterior commissure may accompany deficiencies in the formation of the corpus callosum, as they all relate to a common ancestor, the lamina terminalis: crossing of fiber tracts proceeds from the anterior commissure to the hippocampal structures, and then to the corpus callosum itself.
