Septo-optic dysplasia (SOD) is a neurodevelopmental disorder that affects midline brain structures. Magnetic resonance imaging (MRI) documented midline brain defects include absent septum pellucidum, agenesis of corpus callosum, posterior displacement of pituitary gland and cerebellar hypoplasia. We are reporting a case of a 10-year-old boy who presented with blurring of vision of the left eye with features suggestive of optic nerve hypoplasia. MRI revealed absence of septum pellucidum with pineal gland cyst which has never been reported as a spectrum of this disorder. As pineal gland is a midline brain structure that is derived from diencephalon, this finding may indicate another spectrum of the septo-optic dysplasia.
