Abstract
ABSTRACT: We describe the case of a 48-year-old man suspected to have recurrent colon carcinoma who underwent 68Ga-DOTA-FAPI-04 PET/CT, revealing the presence of an incidentaloma with intense FAPI uptake in the left thyroid lobe. Based on PET/CT findings, malignancy was suspected. Biopsy confirmed the diagnosis of follicular thyroid adenoma with fibrosis and calcification. This case emphasizes the need to increase awareness of this benign lesion in the differential diagnosis of incidental thyroid nodules with high FAPI activity.
