  • Title: Suprasellar germinoma--occult presentation with hypothalamic failure 18 months before diagnosis.
    Author: Bulger K, MacErlean DP, Dinn J, McKenna TJ.
    Journal: Ir J Med Sci; 1989 May; 158(5):117-9. PubMed ID: 2759811.
    Abstract:
    Hormonal evidence of widespread hypothalamic failure, including diabetes insipidus, hyperprolactinaemia, growth failure, hypothyroidism, and adrenal failure, was present in a boy of 14 years. Investigation with computerised axial tomography (CT) and metrizamide encephalography failed to identify any anatomical abnormality at the time of presentation. However, 18 months later papilloedema was noted at which time a suprasellar mass and gross dilatation of the ventricular system were readily identified using CT and a germinoma was subsequently diagnosed and treated. In the light of this experience we recommend that when "idiopathic" hypothalamic failure is diagnosed, imaging procedures, including CT or nuclear magnetic resonance examinations, should be repeated on at least one occasion, after an interval of approximately 6 months.
