Cushings syndrome in pregnancy caused by an adrenal adenoma.

Objective: The description of a rare case of Cushings syndrome caused by an adrenal adenoma in pregnancy with successful treatment.

Case Presentation: 30-ear-old Gravida 3 female was admitted to our hospital with hypertension at the 18th week of gestation. Hormonal analyses revealed primary Cushings syndrome with high plasma cortisol levels and low levels of adrenocorticotropic hormone. Magnetic resonance imaging demonstrated a mass on the right-side of the adrenal gland. Adrenalectomy was performed in the 28th week of gestation and the following histopathology revealed an adrenocortical adenoma. Pregnancy continued until the 38th week of gestation with glucocorticoid replacement therapy and the patient gave birth vaginally to a healthy boy in the 38th week of gestation.

Conclusion: Cushings syndrome in pregnancy rarely occurs; dia-gnosis may be dismissed or determined after birth in most cases. Misdia-gnosis of Cushings syndrome is common because of physiological increase of corticotropin hormones and cortisol levels and overlapping symptoms that can occur even during physiological pregnancy. Cushings syndrome should have a place in the differential dia-gnosis of hypertension in pregnancy (especially before the 20th week of gestation). Analysis of the urinary free cortisol level and circadian rhythm blood cortisol can provide a reasonable strategy to dia-gnose Cushings syndrome in pregnant women. Early dia-gnosis and surgical treatment can significantly reduce maternal and fetal complications.
