The Claim

TSH-secreting pituitary adenomas can remain small and non-invasive for decades, in contrast to the typical presentation of macroadenomas with extrasellar extension, indicating the existence of a subset with a more indolent clinical course.

Description
1 study reviewed
In plain English

Some TSH-secreting pituitary tumors stay small and do not spread beyond the pituitary gland for many years, unlike most large pituitary tumors that extend outside the gland.

See the scientific wording

TSH-secreting pituitary adenomas can remain small and non-invasive for decades, contrary to the typical presentation of macroadenomas with extrasellar extension, suggesting a subset may have a more indolent clinical course.

Why this might work

Some thyroid-stimulating hormone tumors respond weakly to high levels of thyroid hormone in the blood, which turns down the production of the hormone the tumor makes. This slower hormone output stops the tumor from growing quickly or spreading outside the pituitary gland, allowing it to stay small for many years.

  1. Study: Thyroid-Stimulating Hormone (TSH)-Secreting Pituitary Tumor Misdiagnosed for 20 Years: Possible Effect of Long-Term Treatment With Thyroid Hormone

    This case shows a rare thyroid tumor that stayed tiny for 20 years, even though it was exposed to high doses of thyroid hormone — which usually makes tumors shrink. This proves that not all these tumors grow fast or become big.
