A case of congenital adrenal hyperplasia with concomitant abnormalities of steroid 21- and 11 beta-hydroxylase activities.
Abnormalities in the steroid 21-hydroxylase and 11 beta-hydroxylase activities were suspected in a 25-year-old female with congenital adrenal hyperplasia (CAH). The patient showed signs of masculinization such as hirsutism, amenorrhea, and enlarged clitoris, but the blood pressure was normal. Adrenocorticotropic was increased to 200 pg/ml. Plasma levels of deoxycorticosterone and 11-deoxycortisol as well as progesterone and 17-hydroxyprogesterone were elevated. Plasma cortisol level was normal at 5.8 micrograms/dl. CT scan revealed enlargement of the bilateral adrenal glands. This case suggests that enzyme abnormalities in CAH are more diverse than have been generally considered.
