Sarcoidosis is a multisystem disorder of unknown etiology that frequently involves the lymph nodes, lungs, eyes, and skin. The disease can involve any organ system, and noncaseating granulomas are characteristically present. Synthesis of 1,25-dihydroxyvitamin D, the most biologically active form of vitamin D, occurs in granulomatous tissue and may give rise to increases in its concentration in the peripheral circulation and to hypercalcemia and
hypercalciuria
. Infiltration of endocrine organs also occurs. Involvement of the hypothalamus and pituitary can cause primary polydipsia and disordered regulation of thirst; diabetes insipidus, impaired secretion of anterior pituitary hormones (with clinically apparent hypothyroidism, hypogonadism,
hypoadrenalism
, or impaired growth), and increases in serum prolactin may also result. Galactorrhea, however, seldom occurs. Involvement of the thyroid and adrenal glands rarely leads to hypofunction. Involvement of the pancreas rarely occurs but does not produce diabetes mellitus. Involvement of the male reproductive system results in epididymitis and hypogonadism, and involvement of the uterus causes abnormalities in menstrual function.

We report three boys with adrenal hypoplasia congenita (AHC) and additional findings that represent a new syndrome, IMAGe: Intrauterine growth retardation, Metaphyseal dysplasia, AHC, and Genital anomalies. Each presented shortly after birth with growth retardation and severe
adrenal insufficiency
. Each of the three patients had mild dysmorphic features, bilateral cryptorchidism, a small penis, and hypogonadotropic hypogonadism. Skeletal surveys revealed metaphyseal dysplasia in all three and epiphyseal dysplasia in two. The patients had documented or suspected
hypercalciuria
and/or hypercalcemia, resulting in nephrocalcinosis in one and in prenatal liver and spleen calcifications in another. AHC presents most often either as an isolated abnormality, caused by mutations in the DAX1 gene, or as part of an Xp21 contiguous gene syndrome, caused by a deletion of the Duchenne muscular dystrophy, glycerol kinase, and DAX1 genes. All three patients with the IMAGe association had normal creatine kinase levels and no evidence of glycerol kinase deficiency. Sequence analysis of DNA from these patients revealed no mutation in the DAX1- or steroidogenic factor-1-coding sequences, nor was a deletion of DAX1 detected. Identification of the molecular basis of the IMAGe association will give new insight into the pathogenesis of this syndromic relationship involving bone, adrenal cortical, and pituitary development.

IMAGe syndrome is a rare condition, first reported by Vilain et al., in 1999, characterized by intrauterine growth restriction, metaphyseal dysplasia, congenital adrenal hypoplasia, and genital anomalies. Patients with this condition may present shortly after birth with severe
adrenal insufficiency
, which can be life-threatening if not recognized early and commenced on steroid replacement therapy. Other reported features in this condition include,
hypercalciuria
and/or hypercalcemia, craniosynostosis, cleft palate, and scoliosis. We report on a 7-year-old boy with IMAGe syndrome, who in addition to the features in the acronym also has bilateral sensorineural hearing loss which has not been reported in previously published cases of IMAGe syndrome. We discuss the clinical presentation in our patient and review the literature in this rare multisystem disorder.
