As a rare condition characterized by inflammation of the pituitary gland, hypophysitis usually results in hypopituitarism and pituitary enlargement. The most critical outcome of hypopituitarism is caused by secondary adrenal insufficiency. Glucocorticoid deficiency is a life-threatening condition, and patients who develop this deficiency require prompt diagnosis and treatment. However, a delayed diagnosis of hypopituitarism may occur due to its non-specific clinical manifestations. A common presenting sign of glucocorticoid deficiency is hypoglycemia. The amelioration of hyperglycemia has been observed in diabetic patients with adrenal insufficiency. We report the case of a 70-year-old Japanese woman who had suffered from fatigue and anorexia for several months; she was admitted based on refractory hyponatremia (sodium 125-128 mEq/L) and hypoglycemia (glucose 58-75 mg/dL). Laboratory findings and magnetic resonance imaging findings led to the diagnosis of panhypopituitarism caused by autoimmune hypophysitis. After receiving 10 mg/day of hydrocortisone, the patient developed severe hyperglycemia (glucose >500 mg/dL). Undetectable C-peptide levels and positive results of both insulinoma-associated antigen-2 antibodies and insulin autoantibodies indicated that she had experienced a recent onset of type 1 diabetes. The pathophysiological process indicated that overt hyperglycemia could be masked by the deficient action of glucocorticoids even in a diabetic patient with endogenous insulin deficiency. This uncommon case reinforces the importance of the prompt diagnosis and treatment of hypopituitarism. Clinicians should remain aware of the possibility of hidden diabetes when treating hypoglycemia in patients with adrenal insufficiency.

We experienced a case of unruptured internal carotid artery aneurysm improved endocrinological function after the treatment. A 68-year-old woman was admitted to our hospital complaining of general fatigue, dizziness, and decreased visual acuity. Radiological examination revealed unruptured large aneurysm at the right anterior carotid artery compressing on the pituitary gland. We underwent right STA-MCA bypass and trapping of right internal carotid artery. Post-operative course was uneventful. Although visual function was not improved, her endocrinological function was improved 8 months after surgery by thrombosed and shrunken aneurysm. The mechanism of panhypopituitarism due to aneurysm has been suggested to involve mechanical compression on the pituitary gland, pituitary stalk, or hypophyseal artery. Although it was unclear about the improvement of endocrine function after the treatment of aneurysm, some cases could recover the hypopituitarism after enough follow-up period.
