IMAGe syndrome: A complex disorder affecting growth, adrenal and gonadal function, and skeletal development

IMAGe syndrome (intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, genital abnormalities; MIM 300290) is a multisystem disorder with a broad phenotype, which, if unrecognized, may result in major and possibly life-threatening complications. Initial clinical features overlap with those of Russell-Silver syndrome (RSS) and isolated growth hormone (GH) deficiency, conditions from which it must be distinguished. We report an Australian male with adrenal hypoplasia congenita (AHC) in association with IMAGe syndrome. The patient had intrauterine growth restriction (IUGR) and dysmorphic features comprising small, low-set ears, micrognathia, bilateral cryptorchidism, micropenis, and skeletal abnormalities. Signs of adrenal insufficiency occurred at aged 4.6 years. Our patient differs from those previously described by the late onset of adrenal insufficiency and the presence of GH deficiency. IMAGe is a complex syndrome involving dysmorphic features; disorders of growth, gonadal, and adrenal function; and skeletal abnormalities.
