Fibrous dysplasia is a benign proliferative bone disorder. We report a case of polyostotic fibrous dysplasia of the skull base. A 77 year-old man who presented with head discomfort visited our outpatient clinic. Computed tomography revealed pagetoid and sclerotic changes of the sphenoid, ethmoid, and submandibular bones. Biopsy of the ethmoid bone was performed and histopathological examination confirmed a diagnosis of fibrous dysplasia. Because no dysfunction caused by this abnormal lesion was observed, surgical treatment was not performed. The patient was doing well without any sign of disease progression 12 months after the biopsy.
Key words:
fibrous dysplasia, skull base, polyostotic
