Technetium-99m-pentavalent dimercaptosuccinic acid uptake in Hurthle cell tumor of the thyroid.

Abstract

In a patient with metastatic Hurthle cell carcinoma of the thyroid, a subgroup of follicular carcinoma, scintigraphy with pentavalent 99mTc-labeled dimercaptosuccinic acid (V)DMSA showed a significant uptake of the radiopharmaceutical in all tumor sites. We suggest that the accumulation of 99mTc-(V)DMSA within metastases of Hurthle cell thyroid tumor may have a useful role in the staging of these patients, especially when radioiodine fails to concentrate.
