Fibrous Dysplasia Associated with Optic Atrophy-A Case Report

We report the clinical and radiological features of a 13-year-old girl with fibrous dysplasia. She has suffered from progressive loss of vision in the right eye for 3 or 4 months and facial asymmetry for many years. Ophthalmological examination revealed reduced visual acuity to finger counting at 30cm, proptosis, Marcus Gunn pupil, and optic atrophy in the right eye. She had no history of skin pigmentation, precocious puberty, or other endocrine abnormalities. CT scan showed the diffuse thickening of right facial bone with ground-glass appearance and narrowed right optic canal. Later, magnetic resonance imaging revealed a progression of the lesion. We report this rare case and pathophysiology of fibrous dysplasia.
