Patients with empty sella syndrome usually have normal pituitary functions and show no symptom. We report a man with panhypopituitarism who presented as acute psychotic symptoms. This 48-year-old man had three traffic accidents without loss of consciousness 24 years ago. After recovery, he led an uneventful life. He noted pale appearance, cold intolerance and decreased beard and eyebrow gradually in these ten years. Hypotension was found in health exams. Absence of axillary and pubic hair was also noticed. There was no impairment of libido. Two weeks prior to this admission, he suffered from productive cough, sore throat and vomiting, which was treated by herb drugs. Acute-onset conscious change with queer behavior developed when he was working in the office. He was then taken to the emergency department.
On arrival, he was irritable and disoriented. The BP was 114/64 mmHg, temperature 36.5°C and pulse rate 120/min. Physically, he looked pale. Eyebrow was thin and scanty. The chest, heart and abdomen were normal except diminished pigmentation of areola. There was no axillary hair and pubic hair. The testes were soft. Delirium with acute psychotic state was suspected. Hyponatremia (Na 122 mM) and anemia (Hb 9.7 mg/dl) were disclosed. Hypertonic saline was administered. Brain MRI revealed empty sella. His basal hormone levels were: T3 67.5 ng/dl, T4 8.69 μg/dl, hsTSH 0.383 μIU/ml, ACTH 17.6 (8am), 10.8 (4pm) pg/ml, cortisol 1.73 (8am), 6.50 (4pm) μg/dl, hGH 0.44 μg/l, testosterone 0.12 ng/ml, estradiol ＜20 pg/ml. After IV 100 μg LHRH, the serum FSH and LH levels at 0, 15, 30, 60 and 120 minutes were 0.3, 0.3, 0.6, 0.9, 1.2 and ＜0.7, 1.8, 3.8, 3.6, 2.7 mIU/ml, respectively. The serum prolactin and hsTSH levels in response to IV 400 μg TRH at 0, 15, 30, 60 and 120 minutes were 4.7, 7.0, 7.4, 5.7, 5.2 ng/ml and 0.316, 1.320, 2.920, 3.200, 2.100 μIU/ml, respectively. Insulin hypoglycemic test revealed the hGH response at 0, 15, 30, 60 and 120 minutes were 0.25, 0.16, 0.12, 0.16, 0.35 mg/l; ACTH: 3.5, 10.9, 12.1, 10.1, 2.1 pg/ml; cortisol: 2.82, 1.82, 2.38, 1.93, 3.88 μg/dl; prolactin: 5.1, 4.9, 4.8, 4.8, 5.4 ng/ml. Under the impression of empty sella with panhypopituitarism, hormone supplement with IV hydrocortisone 100μg q8h and oral Levothyroxine 100μg qd was administered. His consciousness improved gradually and he was discharged smoothly with oral prednisolone and Levothyroxine. Literatures were reviewed for this rare condition.
