B I Yerevanian, V S Wehby, I S Salti

    Canadian Medical Association Journal
    |May 7, 1977
    PubMed
    Summary

    This study details a 15-year development of anterior pituitary insufficiency in a man, ultimately diagnosed as hypopituitarism of hypothalamic origin. Hormone replacement therapy proved effective.

    Area of Science:

    • Endocrinology
    • Neurology

    Background:

    • A 45-year-old male experienced a sudden onset of left hemiparesis and slurred speech.
    • Over the subsequent 15 years, anterior pituitary insufficiency developed progressively.

    Observation:

    • At age 60, radiographic imaging showed no sellar or suprasellar neoplasm.
    • Endocrinologic assessments included stimulation tests with thyrotropin-releasing hormone (TRH) and luteinizing hormone-releasing hormone (LHRH).

    Findings:

    • The patient presented with symptoms consistent with hypopituitarism.
    • Results indicated hypothalamic origin for the hypopituitarism.
    • Hormone replacement therapy for thyroid, adrenocortical, and testosterone deficiencies was initiated.

    Implications:

    • This case highlights a rare, slow-onset pituitary dysfunction potentially linked to an initial neurological event.
    • It underscores the importance of comprehensive endocrinologic evaluation in cases of unexplained pituitary insufficiency.
    • Effective management with hormone replacement therapy was demonstrated.
