| Popis: | Hypercortisolism is a multisystem disorder that results from inappropriate and excessive glucocorticoid secretion and loss of normal feedback mechanisms of the hypothalamic-pituitary axis. It is broadly divided into adrenocorticotropic hormone (ACTH) dependent and ACTH-independent categories. Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare cause of ACTH-independent hypercortisolism, accounting for less than 2% of cases. It usually presents as hypertension, metabolic abnormalities, thromboembolic, cardiovascular, or endocrine disorders but rarely as a neuropsychiatric illness. Therefore, a delay in the diagnosis and management of cognitive illnesses substantially increases morbidity in these patients. Herein, we report a case of severe psychosis due to Cushing's syndrome with PBMAH. A 49-year-old male with a past medical history of diabetes and hypertension presented with acute onset of confusion. The patient’s uncontrolled hypertension, hypokalemia, metabolic alkalosis, and resistant psychosis to various psychotropic medications raised the suspicion of an underlying metabolic disorder. Further workup revealed an inappropriate suppression of morning (AM) cortisol after administration of dexamethasone and elevated values of serum AM cortisol and 24-hour urinary cortisol, in addition to low ACTH. Computed tomography (CT) of the abdomen and pelvis with intravenous (IV) contrast was performed to evaluate the adrenal gland which showed multiple nonspecific adrenal nodules bilaterally measuring between 3.5 cm - 4.5 cm. The patient was hence diagnosed with hypercortisolism secondary to PBMAH. The patient was treated with ketoconazole after he refused surgery as a treatment option and was noted to have significant improvement in his psychosis within a week, along with improvement of his hypertension, electrolyte abnormalities, and a significant decrease in the 24-hour urine cortisol level. Neuropsychiatric illness is a rare manifestation and an unusual initial presenting symptom of Cushing’s syndrome secondary to primary bilateral macronodular adrenal hyperplasia. A delay in diagnosis often subjects these patients to unnecessary psychotropic medications and prolonged psychiatric hospitalizations. Hence, clinicians must be cognizant of this rare entity when making a diagnostic evaluation to prevent subsequent morbidity and mortality. |
