Two Girls With Adrenal Insufficiency and Failing Gonads

Abstract

Abstract Congenital lipoid adrenal hyperplasia (CLAH) is a rare cause of adrenal insufficiency caused by mutations in the steroidogenic acute regulatory (StAR) gene. Patients classically present with adrenal crisis in early infancy and female external genitalia irrespective of chromosomal sex. We report 2 Chinese patients with normal female external genitalia presenting with salt wasting in the neonatal period. However, the diagnosis of CLAH was made only during pubertal years when they developed hypergonadotropic hypogonadism. One of them was subsequently found to have a 46XY karyotype and gonadectomy was performed at age 15 years. The other patient developed gonadal insufficiency and polycystic ovaries after menarche with hemorrhage into ovarian cysts requiring cystectomy. These 2 cases illustrate the importance of recognizing atypical features in neonates presenting with adrenal crisis. In managing the newborn with adrenal insufficiency and female-appearing external genitalia, the possibility of sex reversal and diagnosis of CLAH should be considered. Accurate delineation of internal pelvic organs using reliable imaging modalities or even laparoscopy, together with careful interpretation of clinical and laboratory findings, are crucial to accurate diagnosis and subsequent management.
