Adrenal gland size was evaluated in six infants with congenital adrenal hyperplasia. All of the infants had a severe deficiency of the 21-hydroxylase enzyme resulting in the salt-losing form of congenital adrenal hyperplasia. The adrenal measurements were compared with those of 40 consecutive age-matched, asymptomatic infants. Mean adrenal length was 14.4 mm and width was 1.9 mm in asymptomatic infants, whereas in infants with congenital adrenal hyperplasia mean adrenal length was 23.7 mm and width was 5.3 mm. Although infants with congenital adrenal hyperplasia may have normal-sized adrenal glands, mean length measurements of 20 mm or greater and mean width measurements of 4 mm or greater suggest the diagnosis.
对六名先天性肾上腺皮质增生症婴儿的肾上腺大小进行了评估。所有婴儿均严重缺乏21-羟化酶，导致出现失盐型先天性肾上腺皮质增生症。将这些婴儿的肾上腺测量值与40名年龄匹配、无症状的连续婴儿的测量值进行了比较。无症状婴儿的肾上腺平均长度为14.4毫米，宽度为1.9毫米，而先天性肾上腺皮质增生症婴儿的肾上腺平均长度为23.7毫米，宽度为5.3毫米。虽然先天性肾上腺皮质增生症婴儿的肾上腺大小可能正常，但平均长度测量值在20毫米或以上且平均宽度测量值在4毫米或以上提示可能患有该病。
