Disappearance of a hyperfunctioning thyroid nodule following TSH stimulation

H Kammer, M O Loveless

    Journal of Nuclear Medicine : Official Publication, Society of Nuclear Medicine
    |October 1, 1978
    PubMed
    Summary

    Thyroid stimulating hormone (TSH) stimulation caused transient hyperthyroidism in a patient with a large autonomous thyroid nodule. The nodule subsequently disappeared, indicating a potential new therapeutic approach for autonomous thyroid nodules.

    Area of Science:

    • Endocrinology
    • Thyroidology
    • Molecular Endocrinology

    Background:

    • Autonomous thyroid nodules can cause hyperthyroidism.
    • Thyroid stimulating hormone (TSH) typically stimulates thyroid growth and function.
    • The role of TSH in established autonomous nodules is complex.

    Observation:

    • A patient presented with a large, hyperfunctioning autonomous thyroid nodule.
    • Exogenous TSH was administered to the patient.
    • The patient experienced transient hyperthyroidism and reduced radioiodine uptake post-TSH administration.

    Findings:

    • The hyperfunctioning autonomous thyroid nodule resolved after TSH stimulation.
    • This suggests a paradoxical effect of TSH on autonomous nodules.
    • Radioiodine uptake provides insight into nodule activity.

    Implications:

    • TSH stimulation may offer a novel therapeutic strategy for managing autonomous thyroid nodules.
    • Further research is warranted to elucidate the mechanisms behind TSH-induced nodule regression.
    • This finding could impact the treatment paradigm for toxic thyroid adenomas.
