Congenital adrenal hyperplasia refers to a spectrum of autosomal recessive inherited disorders of steroidogenesis most commonly identified on newborn screenings. We describe a young woman who presented with abdominal pain and on subsequent imaging was found to have features of congenital adrenal hyperplasia. Imaging findings, treatment, and potential complications are discussed.
BACKGROUND Congenital lipoid adrenal hyperplasia presents with adrenal insufficiency and sex reversal in 46XY genetic males. CASE CHARACTERISTICS Two patients (46 XY karyotype), one having ambiguous genitalia and other having female external genitalia, presented with adrenal crisis at 6 months and 4 weeks of age, respectively. OBSERVATION Steroidogenic Acute Regulatory Protein gene sequenci...
Congenital adrenal hyperplasia is attributed to inherited enzyme defects in the adrenal cortex. The classical form results in reduced production of cortisol and aldosterone, accompanied by an increase in production of adrenal cortical androgens. This causes virilisation in girls, adrenocortical failure and early puberty in both sexes. This article describes the genetics, clinical picture, diagn...
An adrenal cortical tissue tumor developed in a patient with poorly controlled salt-losing congenital adrenal hyperplasia. A 16-year-old girl became progressively virilized from 13 to 16 years of age. Base line serum progesterone, 17-hydroxyprogesterone, and testosterone levels were high and there was a diurnal pattern of the hormones. Initially elevated urinary 17-ketosteroid and serum steroid...
Congenital adrenal hyperplasia consists of a heterogenous group of inherited disorders due to enzymatic defects in the biosynthetic pathway of cortisol and/or aldosterone. This results in glucocorticoid deficiency, mineralocorticoid deficiency, and androgen excess. 95% of CAH cases are due to 21-hydroxylase deficiency. Clinical forms range from the severe, classical CAH associated with complete...
Congenital adrenal hyperplasia associated with deficiency of steroid 21-hydroxylase is the most common inborn error in adrenal function and the most common cause of adrenal insufficiency in the pediatric age group. As patients now survive into adulthood, adult health-care providers must also be familiar with this condition. Over the past several years, F1000 has published numerous commentaries ...
Congenital lipoid adrenal hyperplasia (lipoid CAH) is the most fatal form of CAH, as it disrupts adrenal and gonadal steroidogenesis. Most cases of lipoid CAH are caused by recessive mutations in the gene encoding steroidogenic acute regulatory protein (StAR). Affected patients typically present with signs of severe adrenal failure in early infancy and 46,XY genetic males are phenotypic females...
The incidence of congenital adrenal hyperplasia in Saudi Arabia and the frequency of the carrier rate are not well known. Both figures should be high, considering the commonness of first-degree consanguinity in this part of the world. We present 25 cases of congenital adrenal hyperplasia, most of them due to a defect of the 21 hydroxylase enzyme, diagnosed and followed over three years at Sulei...
Congenital adrenal hyperplasia (CAH) is an inherited disorder of steroidogenesis characterized by adrenal insufficiency and variable degrees of hyper or hypo androgeny manifestations, depending of the type and the severity of the disease. A classic form presents with prenatal onset of virilization caused by severe enzyme deficiency and is distinguished from a non-classic form with mild enzyme d...
