Septo-optic dysplasia with cerebellar hemiagenesis - a rare congenital malformation.

Septo-optic dysplasia (De morsier’s syndrome) is a rare congenital malformation of the central nervous system and represents a clinical spectrum rather than a specific entity. It is defined by any combination of pituitary hypoplasia with or without consequent panhypopituitarism,optic nerve hypoplasia and midline neurological abnormalities such as absent septum pellucidum and corpus collasum agenesis or thinning. Septo-optic dysplasia with associated cerebellar hemiagenesis is a much rarer congenital anomaly and may represent one end of this spectrum.
