Congenital cystic eye: features on MRI.

Congenital cystic eye is a rare cause of cystic orbital lesion. The condition is recognized at birth as a large orbital mass in place of a normal eye. Only 29 cases have been reported previously. We report a case of unilateral congenital cystic eye with multiple brain anomalies in the form of agenesis of corpus callosum and grey matter heterotopias. In this case report we highlight the MRI features of this entity, which have not been described previously in the literature.
