67-year-old female with nontoxic single thyroid nodule. RIGHT LOBE MEASUREMENTS: 6.1 x 3.4 x 2 cmLEFT LOBE MEASUREMENTS: 5.7 x 2.4 x 1.5 cmISTHMUS MEASUREMENTS: 0.4 cmRIGHT LOBE: Parenchyma is heterogeneous with hyperechoic and hypoechoic areas. This may be seen with thyroiditis. Large solid nodule which is mildly hypoechoic with internal cystic component in the midportion of the gland measuring 1.3 x 2.7 x 2.9 cm. This corresponds to the CT abnormality. In the inferior right lobe is a minimally hypoechoic, rounded solid mass measuring 1 x 1.2 x 1.6 cm with a partial halo. Smaller hypoechoic nodules are present as well.LEFT LOBE: Parenchyma is heterogeneous with hyperechoic and hypoechoic areas. In the anterior, midportion of the left lobe is a hypoechoic and mildly heterogeneous mass, measuring 0.6 x 1.3 x 1.5 cm. Very hypoechoic but heterogeneous, posterior mass in the inferior left lobe is believed to be extrathyroidal, measuring 1 x 0.9 x 1.3 cm alternately this could represent a somewhat pedunculated or exophytic left thyroid nodule. There are also other slightly hypoechoic nodules that are not adequately defined for measurement. Small cystic nodules are present as well. ISTHMUS: Heterogeneous. Small cystic areas with comet tail consistent with colloid.PARATHYROID GLANDS: See above. Potential parathyroid adenoma on the left.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
Multiple, bilateral thyroid nodules with a background heterogeneous parenchyma.Probable extrathyroidal mass on the left.
