Fluorodeoxyglucose Positron Emission Tomography in Primary Thyroid Lymphoma with Coexisting Lymphocytic Thyroiditis

Abstract

The frequent association of LT with primary thyroid lymphoma and the overlap of their clinical and pathologic findings pose a significant diagnostic challenge. While other imaging techniques are helpful in evaluating anatomic local and regional extent of primary thyroid lymphoma, 18F-FDG PET/CT can be of an added value in evaluating its metabolic activity and detecting regional and distant disease as well as in assessing response to treatment.
