Congenital cystic eye with corpus callosum hypoplasia: MRI findings.
Congenital cystic eye is an extremely rare congenital anomaly with fewer than 40 cases reported. Although its aetiology remains unknown, it results from partial to complete failure in invagination of the primary optic vesicle. It is usually unilateral and presents as a heterogeneous lesion with a cyst bulging the upper eyelid and a solid component consisting in neuroglial tissue. We describe a rare case of congenital cystic eye with corpus callosum hypoplasia with special focus on the magnetic resonance imaging (MRI) features and their role in the diagnosis. We conclude that MRI is not only useful in the diagnosis and management of this rare entity, but it can also be helpful in diagnosing associated brain abnormalities.
