History of hyperthyroidism. RIGHT LOBE MEASUREMENTS: 5.9 x 2.6 x 2.6 cmLEFT LOBE MEASUREMENTS: 6.1 x 2.4 x 3.6 cmISTHMUS MEASUREMENTS: 1 mmRIGHT LOBE: Multiple thyroid nodules with the largest being a complex predominantly solid isoechoic nodule measuring 2.0 x 1.0 x 2.2 cm with a coarse 4 mm calcification and punctate echogenic foci (several of which show comet tail or reverberation artifact supportive of colloid, many too small to adequately characterize) and vascularity. It is well-defined.Dorsally there is a 0.9 x 1.0 x 1.0 cm hypoechoic well-defined solid nodule, most likely colloid.LEFT LOBE: Complex solid/cystic isoechoic nodule measuring 2.1 x 3.5 x 3.7 cm with punctate echogenic foci (again some demonstrating comet tail artifact suggestive of colloid) and vascularity. It is well-defined.ISTHMUS: Hypoechoic 0.9 x 0.8 cm left isthmus nodule without significant vascularity or suspicious sonographic features.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
Multinodular thyroid with heterogeneous mixed cystic/solid nodules seen bilaterally, see discussion above.
