Reason: increased FDG activity within the right thyroid lobe on PET/CT RIGHT LOBE MEASUREMENTS: 6.2 x 2.8 x 1.9 cm.LEFT LOBE MEASUREMENTS: 4.7 x 1.9 x 1.1 cm.ISTHMUS MEASUREMENTS: Up to 0.8 cm in thickness.RIGHT LOBE: Mildly heterogeneous background parenchymal echotexture. Midpole nodule measuring 2.7 x 1.4 x 1.9 cm which is predominantly solid, isoechoic to the thyroid gland, demonstrates mild internal vascularity, has a hypoechoic halo, and lacks suspicious microcalcifications. Overall, this nodule is of intermediate suspicion for neoplasm.LEFT LOBE: Mildly heterogeneous parenchymal echotexture including a couple subcentimeter hypoechoic nodules.ISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
Dominant nodule within the right thyroid gland corresponding to increased uptake on recent PET scan is of intermediate suspicion for neoplasm and would be amenable to fine-needle aspiration.
