Septo-Optic Dysplasia - ț̢
A condition resulting from congenital malformations involving the brain. The syndrome of septo-optic dysplasia combines hypoplasia or agenesis of the SEPTUM PELLUCIDUM and the OPTIC NERVE. The extent of the abnormalities can vary. Septo-optic dysplasia is often associated with abnormalities of the hypothalamic and other diencephalic structures, and HYPOPITUITARISM.
