The agenesis of the corpus callosum (ACC) supposes an interhemispheric disconnection due to lack of formation of said structure in the embryonic development. Prevalence: 0.3-0.5% in the general population and 2.3% in people with disabilities. It is associated with prematurity and advanced maternal age. Agenesis of the corpus callosum is a malformation that can occur in isolation or in association with other systemic or central nervous system disorders and is one of the most common malformations in the brain, with an estimated prevalence of 1 in 4,000 live births. Among the most common clinical findings are mental retardation, visual problems, and seizures. Prenatal diagnosis can be made by ultrasound and magnetic resonance imaging from the 20th week of gestation. Postnatal diagnosis can be made by ultrasound, computed tomography, and magnetic resonance imaging. Currently, there is no specific treatment, although it has been proposed to start an early stimulation program and, if possible, a psychomotor rehabilitation program that offers improvement in motor and learning disorders.
