Endocrine function in patients with suprasellar and hypothalamic tumours.

O Korsgaard, J Lindholm, P Rasmussen

    Acta Endocrinologica
    |September 1, 1976
    PubMed
    Summary

    Non-pituitary suprasellar tumors, including craniopharyngiomas and hypothalamic gliomas, frequently cause severe pituitary hormonal disturbances. Other tumors like cysts and meningiomas show less severe issues, often related to tumor size.

    Area of Science:

    • Neuroendocrinology
    • Neurosurgery
    • Oncology

    Background:

    • Suprasellar tumors are neoplasms located above the pituitary gland.
    • These tumors can impact pituitary function and hormone production.
    • Understanding the relationship between tumor type, size, and endocrine dysfunction is crucial.

    Purpose of the Study:

    • To investigate pituitary function in patients with non-pituitary suprasellar tumors.
    • To correlate tumor type and size with the severity of hormonal disturbances.
    • To assess the impact of specific suprasellar tumor types on endocrine health.

    Main Methods:

    • Studied pituitary function in 35 consecutive patients.
    • Classified tumors into types: craniopharyngiomas, hypothalamic gliomas, suprasellar cysts, meningiomas, and optic nerve gliomas.
    • Utilized pneumoencephalography to assess tumor size and impact.

    Main Results:

    • Craniopharyngiomas and hypothalamic gliomas consistently presented with severe hormonal disturbances.
    • Suprasellar cysts, meningiomas, and optic nerve gliomas exhibited less severe hormonal issues.
    • Tumor size, assessed via pneumoencephalography, correlated with the extent of hormonal alterations; larger tumors caused more significant dysfunction.

    Conclusions:

    • The type and size of suprasellar tumors significantly influence pituitary function.
    • Craniopharyngiomas and hypothalamic gliomas are associated with profound endocrine deficits.
    • Less invasive tumors may cause milder, size-dependent pituitary dysfunction.
