  • Title: A case of intrasellar craniopharyngioma.
    Author: Hiramatsu K, Takahashi K, Ikeda A, Arimori S.
    Journal: Tokai J Exp Clin Med; 1987 May; 12(2):135-40. PubMed ID: 2835833.
    Abstract:
    A 71-year-old man was referred to Tokai University Hospital because of cold intolerance, slow speech and slowing down of his intellectual and motor activities. Free thyroxine index, and free T-4 and T-3 levels were low (1.4, 0.7 ng/dl and 0.4 ng/ml, respectively) with normal TSH (2.5 microIU/ml). A skull X-ray showed enlargement of the sella turcica and his CT scan revealed an intrasellar mass. LH, FSH, ACTH and PRL did not rise in response to the intravenous administration of LH-RH and insulin. A diagnosis of pan-hypopituitarism due to a pituitary tumor was established. The release of ACTH and cortisol was restored under stimulation of CRF or lysine vasopressin. TSH responded to TRH in a delayed manner. The pituitary tumor was removed by a transsphenoidal operation and diagnosed histologically as craniopharyngioma. Our hospital has experienced nine cases of craniopharyngioma in the last 10 years but the present case was the only intrasellar craniopharyngioma.
