A variant of the syndrome of spinal arachnoid cysts with multiple congenital defects.

We report an apparently unique case of multiple spinal intradural arachnoid cysts in association with distichiasis, late onset lower limb lymphoedema, and previously unrecognized features of associated bilateral megaureters, Arnold Chiari malformation with hydrocephalus and syringomyelia. The literature on this unusual group of congenital malformations is reviewed.
