Reason: 66 y/o man with a right thyroid nodule. RIGHT LOBE MEASUREMENTS: 8.1 x 4.3 x 2.9 cm.LEFT LOBE MEASUREMENTS: 5.7 x 3.1 x 1.8 cm.ISTHMUS MEASUREMENTS: Up to 3 mm in thickness.RIGHT LOBE: Mildly heterogeneous background parenchymal echogenicity. Partially visualized heterogeneous predominantly hypoechoic solid nodule at the inferior pole measuring 4.5 x 4.0 x 4.0 cm which extends substernally. The nodule demonstrates some internal vascularity, and a single dystrophic appearing calcification is noted.LEFT LOBE: Mildly heterogeneous background parenchymal echogenicity. No discrete nodules identified.ISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
Partially imaged dominant thyroid nodule in the right inferior pole extending substernally which is of intermediate suspicion for neoplasm.
