The roentgenographic appearance in the cranial bones ranges from small, simple translucent areas to massive, sclerotic overgrowth. In many instances the disease is easily recognized but, due to the wide range of its roentgen manifestations, it can simulate and be imitated by numerous other conditions, particularly the hyperostoses associated with a meningioma. In order to increase our knowledge of the natural history and the varied roentgenographic appearance of this disease, we have reviewed the literature and analyzed films and clinical records of 46 patients with fibrous dysplasia involving the skull and facial bones seen at the Columbia-Presbyterian Medical Center.
