Isolated primary thyroid lymphoma and lesion in the thyroid gland presenting as a lymphoma, both are uncommon entities. This subgroup of thyroid malignancies is managed in different ways as compared to common thyroid malignancies. A 63-year-old male diagnosed as non-Hodgkin’s lymphoma of the thyroid gland underwent for F-18 fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT). It revealed isolated FDG avid soft tissue mass in left lobe of thyroid gland. After two and six cycles of chemotherapy, PET-CT was perfomed and response assessed in Deauville scores.
