Chiari malformation in female monozygotic twins

Abstract

We describe the cases of female monozygotic twins who presented almost synchronously with symptomatic Chiari malformation type I. Both were successfully treated with foramen magnum decompression. We analyse these findings in the context of previously reported cases and discuss the genetic implications.

Key words:

• Chiari type I malformation
• posterior fossa
• surgical decompression
• magnetic resonance imaging
