title: [Fibrous dysplasia involving sphenoid and occipital bone: one case report and literature review].
abstract: OBJECTIVE
  To study the clinical manifestation, radiograph features, pathology, diagnosis and treatment of fibrous dysplasia in cranial bone.
  
  
  METHODS
  A case of fibrous dysplasia involving sphenoid and occipital is reported and literature were reviewed.
  
  
  RESULTS
  The most common complaint were headache, proptosis, diplopia, or visual changes. Distinguishing features of fibrous dysplasia on CT include "ground-glass" appearance, bone fiber anisotrophy, aneurysmal bone cyst formation and thickness of the cranial cortices. Fibrous dysplasia could be exactly diagnosed by pathology. Computed tomography was also a choice for diagnosis.
  
  
  CONCLUSIONS
  Fibrous dysplasia involving the cranial bone can present in myriad ways. Modern imaging modalities and histopathologic analysis is required to make accurate diagnosis. Surgery, particularly in a challenging region such as sphenoid and occipital bone, should preserve the existing function for the patients with functional impairment or a cosmetic deformity.
