Abstract
Introduction
Cushing syndrome is a rare disorder with a variety of underlying etiologies, that can be exogenous or endogenous (adrenocorticotropic hormone (ACTH)-dependent or ACTH-independent). The current study aims to report a case of ACTH-independent Cushing syndrome with adrenal adenoma and nonfunctioning pituitary adenoma.
Case report
A 37–year–old female presented with amenorrhea for the last year, associated with weight gain. She had a moon face, buffalo hump, and central obesity. A 24-hour urine collection for cortisol was performed, revealed elevated cortisol. Cortisol level was non-suppressed after administering dexamethasone. MRI of the pituitary region revealed a pituitary microadenoma, and the CT scan of the abdomen with adrenal protocol revealed a left adrenal adenoma.
Discussion
Early diagnosis may be postponed due to the variety of clinical presentations and the referral of the patient to different subspecialists based on their dominant symptoms (gynecological, dermatological, cardiovascular, psychiatric); it is, therefore, critical to consider the entire clinical presentation for correct diagnosis.
Conclusion
Due to the diversity in the presentation of CS, an accurate clinical, physical and endocrine examination is always recommended.
Cushing syndrome (CS) is a rare disorder with a variety of underlying etiologies.
CS is expected to affect 0.2 to 5 people per million per year.
Adrenal-dependent CS is an uncommon variant of CS.
This study reports a rare occurrence of pituitary and adrenal adenoma with CS.
