AbstractA 59-year-old man was admitted to our hospital with hyponatremia. An endocrine examination indicated panhypopituitarism, and magnetic resonance imaging revealed a mass-like lesion in the pituitary gland. Sinus endoscopy revealed a fungal mass in the sphenoid sinus, and the patient was diagnosed with hypopituitarism due to aspergillosis of the central nervous system (CNS). The patient's hyponatremia resolved with hydrocortisone replacement. Although the right internal carotid artery was eventually occluded, antifungal medications were administered for the aspergillosis, and the patient's general condition improved. The patient's CNS lesions have remained under control since discharge. This is the first case to suggest that ACTH secretion may be relatively preserved in Aspergillus-induced hypopituitarism.
