title: Bilateral exophthalmos: Report of a case and review of a fibroblast growth factor receptor 2 mutation associated with non-penetrant Crouzon syndrome.
abstract: The differential diagnosis of exophthalmos requires careful examination to identify potentially serious aetiologies. We present the case of a child with exophthalmos in whom genetic analysis identified a mutation in the fibroblast growth factor receptor 2 associated with Crouzon syndrome. The variable presentation should remind paediatricians to consider mutations in fibroblast growth factor receptor 2 among the aetiologies of exophthalmos.
