Abstract

F-18 FDG is the most widely used tracer in molecular imaging and it isapplied for many purposes mainly in malignant diseases. Incidental findingare common in FDG-PET/CT imaging and includes benign and malignantlesions. Among the rare tumors , adrenal oncocytomas are uncommonfindings and incidental findings of thyroid malignancies are not rare.Oncocytoma is a rare adrenocortical tumor and majority of bulky adrenaltumors are benign with uncertain incident of malignancy. In this study,we are reporting a 37-year-old man with two incidental malignanciesdetected by FDG-PET-CT. He has no symptoms has no blood and hormonalabnormalities.The scan demonstrated intense heterogeneous FDG uptake within thebulky oval shaped lesion in the left adrenal gland. Accordingly, openadrenalectomy was performed and diagnosis of adrenocortical carcinomaoncocytic type was established. Furthermore, a focal FDG uptake wasidentified in the right thyroid lobe and histopathology findings wereconsistent with well-differentiated papillary thyroid cancer. FDG playsa great role in identifying primary rare lesions and also detection ofincidental findings at unexpected sites.
