Used for a wide range of cancers, nivolumab has been reported to cause immune-related adverse events, including isolated adrenocorticotropic hormone deficiency (IAD). We report an 81-year-old woman with malignant mesothelioma who presented with abdominal pain after eight courses of nivolumab therapy, leading to the diagnosis of nivolumab-induced IAD. We should consider adrenal insufficiency (AI) when a patient on nivolumab complains of abdominal pain and has no other explanatory findings. Infusion-resistant hypotension and hyponatraemia can further suggest AI.
