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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.

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.
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.
What the research says
1 studyThis 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.
