Septo-optic dysplasia is a congenital anomaly with diverse phenotypes from normal to mixtures of visual abnormality, endocrine dysfunction, psychomotor retardations and epileptic seizures. It is characterized by optic atrophy, pituitary dysfunction and midline structure abnormalities in corpus callosum or septum pellucidum. Diagnosis of septo-optic dysplasia plus is made when cortical malformations accompanied. Here we report a middle-aged woman with septo-optic dysplasia plus having unilateral optic atrophy, agenesis of septum pellucidum and cortical malformations.
