Chiari Malformation Caused by Craniometaphyseal Dysplasia: Case Report and Review of Literature

Abstract

Chiari malformation is commonly considered a congenital condition. To our knowledge, reports of progressively symptomatic Chiari Ι malformation with craniometaphyseal dysplasia are rare. The authors present a case of progressively symptomatic Chiari Ι malformation occurring in an 11-month-old infant with craniometaphyseal dysplasia. The patient presented with a typical facial appearance and radiological skeletal survey. Posterior fossa decompression was performed. In the meantime, the patient was given Rocaltrol® (calcitriol) and adopted a low calcium diet. His neurological symptoms were markedly improved after surgery. The clinical presentations, radiographical features and prognosis of the patient are discussed with reference to the literature.

Key words

Chiari malformation - bone dysplasia - craniometaphyseal dysplasia - posterior fossa decompression
