Arnold Chiari malformation type 1 with cerebellar tonsil herniation through foramen magnum: A case report

Arnold Chiari malformation is an uncommon disorder that mainly occurs in the posterior fossa. The prevalence is relatively unknown, but it is estimated that around one child will suffer from Arnold Chiari malformation in every 1000 births. In this case study, we presented a case of a 45-year-old female suffering from Arnold Chiari malformation type I. Following her clinical examination, she underwent foramen magnum decompression surgery.
