Case 1: A 65- year-old man was accidentally injured by wooden hammer on his top of head on 34 years before. He was suffered from vomiting, diarrhea and hypotension, and the laboratory examination revealed increased CRP level, hyponatremia and decreased plasma cortisol and ACTH levels, suggesting isolated ACTH deficiency and Crohn disease diagnosed by colonoscopic biopsy, and finally transferred to University Hospital. LH-RH, TRH, CRH and GHRP stimulation tests showed normal response of plasma pituitary hormones except for no response of plasma ACTH and cortisol levels by CRH stimulation. ACTH stimulation test showed no response of plasma cortisol levels although hydrocotisone replacement therapy had already been started. MRI imaging showed bottom of anterior lobe was crushed and pituitary gland was atrophied, which suggested brain might be injured by any strong trauma.
