Familial megalencephaly with dilated Virchow-Robin spaces in magnetic resonance imaging: an autosomal recessive trait?

We report the unusual occurrence of progressive megalencephaly and dilated periventricular cystic Virchow-Robin spaces on magnetic resonance imaging in two siblings of a Turkish family. Both affected children in addition presented with psychomotor retardation. Since the index patients were of different gender and their parents were consanguineous, this constellation of findings is suggestive of an autosomal recessive trait.
