The mucopolysaccharidoses are a group of inherited lysosomal storage diseases that are caused by a deficiency of specific enzymes. The acid mucopolysaccharides are stored in tissue and excreted in large quantities in the urine. The storage of this material leads to effects on a wide variety of tissues and to remarkable changes in morphologic features. Winchester syndrome is a rare disorder in the group of mucopolysaccharidoses. This article is a report of a case with classic clinical, radiologic, and biochemical characteristics of the Winchester syndrome.
