Carcinomas can appear as scintigraphically hot thyroid nodules.
Is it true that carcinomas can appear as scintigraphically hot thyroid nodules?
Yes. Although hyperfunctioning thyroid nodules are usually benign, multiple case reports and reviews demonstrate that various types of thyroid carcinomas can occasionally present as scintigraphically hot nodules.
Verdict: SUPPORTED · 8 sources for, 0 against · Last checked
The claim states that carcinomas can appear as scintigraphically hot thyroid nodules. Multiple papers in the provided literature (including reviews, case series, and individual case reports) explicitly document instances where thyroid carcinomas (such as papillary, follicular, and medullary variants) appeared as hot or hyperfunctioning nodules on thyroid scintigraphy. Therefore, the evidence strongly supports the claim.
