Abstract

Introduction: One of the less common and more life-threatening etiologies of adrenal insufficiency is immune checkpoint inhibitor (ICI)-induced primary adrenal insufficiency (PAI). Patients typically present with fatigue, malaise, and nausea and are treated empirically with hydrocortisone.

Case Report: We present the case of a 59-year-old female who presented with hypotension, which initially was thought to be due to hypovolemia or medication-related, but was ultimately found to have PAI.

Conclusion: This case highlights the importance of early detection of ICI-induced primary adrenal insufficiency, given its associated morbidity and mortality and its incidence in patients with a history of immunotherapy.
