title: Elastographic presentation of synchronous renal cell carcinoma metastasis to the thyroid gland.
abstract: Synchronous metastasis of renal cell carcinoma (RCC) are extremely uncommon with only few sporadic cases published in the literature and data on their elastographic appearance are lacking. Here we described a case of woman with multinodular goiter bearing a RCC metastasis, in which exhaustive ultrasonographic and qualitative elastographic evaluation were performed. The metastatic lesion presented some suspicious ultrasonographic features but was mainly "soft" at qualitative elastographic evaluation, suggesting that RCC metastasis may represent a possible pitfall for the qualitative elastographic evaluation of thyroid nodules.
