Giant ovarian cyst in a woman with congenital adrenal hyperplasia disappeared after adjustment of glucocorticoid therapy.

摘要

The patient had demonstrated clitoral enlargement at 2 years of age and was brought to a local hospital by her parents. Thereafter, she was treated with hydrocortisone under a diagnosis of congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-OHD). She had menarche at 12 years old and menstruation had been regular thereafter. However, she developed oligomenorrhea at 22 years old. She consulted our hospital in 2006, at the age of 28, when she married. Her ACTH level was 422 pg/mL, 17-hydroxyprogesterone (17-OHP) 304 ng/mL, testosterone (T) 1.27 ng/mL in the morning after fasting overnight, and was taking hydrocortisone 40 mg/day. An ovarian cyst measuring 85×62 mm was observed on abdominal computed tomography in July 2006. At that time, 17-OHP was 2.5 ng/mL, T 0.09 ng/mL in the early morning after an overnight fast, while taking hydrocortisone 20 mg in the morning and 10 mg in the evening, and prednisolone 2 mg in the evening. We were planning the excision of the ovarian cyst, but it had disappeared on ultrasonography by November 2006. Thereafter, she became pregnant naturally and gave birth to a female infant by caesarean section in February 2008.
