This case was challenging because Mr. A did not initially respond to psychiatric intervention, his psychiatric symptoms worsened after transsphenoidal resection of the pituitary adenoma, and his symptoms were alleviated only after psychiatric medications were re-initiated following surgery. This case highlights the importance of considering an underlying medically diagnosable and treatable cause of psychiatric illness, and illustrates the complex ongoing management that may be necessary to help a patient with this condition achieve their baseline. Further, Mr. A’s case shows that the absence of response to standard psychiatric therapies should warrant earlier laboratory and/or imaging evaluation prior to or in conjunction with psychiatric referral. Additionally, testing for cortisol levels is not typically done for a patient with treatment-resistant anxiety, and this case highlights the importance of considering hypercortisolism in such circumstances.
Bottom Line
Consider testing cortisol levels in patients with treatment-resistant anxiety and insomnia, because cortisol plays a role in Cushing’s disease and anxiety. The severity of psychiatric manifestations of Cushing’s disease may correlate with cortisol levels. Treatment should focus on symptomatic management and underlying etiology.
