[Endocrinological evaluation of sellar and suprasellar tumor cases (the seventh report)--endcrinological study on four cases of pituitary adenoma with intratumoral hemorrhage (author's transl)].

Four cases of pituitary adenoma with intratumoral hemorrhage were studied endocrinologically. 1) It would be suggested that ACTH and TSH secretion of these cases was strongly impaired but LH, FSH and PRL secretion was fairly preserved immediately after hemorrhagic episode. 2) Two of these four cases revealed normal TSH secretion and normal thyroid function following the period of excessive TSH secretion and impaired thyroid function.
