53-year-old female for follow-up thyroid nodules. RIGHT LOBE MEASUREMENTS: 6 x 2.2 x 2.8 cmLEFT LOBE MEASUREMENTS: 6.7 x 2.1 x 3 cmISTHMUS MEASUREMENTS: 1.1 cmRIGHT LOBE: In the right lobe, there is again noted and almost isoechoic mass with at least a partial hypoechoic rim measuring 0.7 x 0.6 x 0.7 cm without significant change.LEFT LOBE: Complex cystic nodule in the midportion of the left lobe anteriorly measures 1.5 x 1.7 x 1.8 cm, increased in size when compared to prior and also increase in complexity. Posterior hypoechoic and likely spongiform nodule measures 0.6 x 0.7 x 0.9 cm without change.ISTHMUS: Previously noted spongiform-appearing isthmus nodule has changed in appearance, now without obvious cystic component and with poorly defined borders measuring 0.8 x 1.4 x 1 cm, significantly decreased in size when compared to prior exam.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Increase in size of complex cystic left thyroid nodule.2. Stable right and posterior left thyroid nodules.3. Significant decrease in size of prior spongiform nodule, now with ill-defined margins and no obvious cystic component. Presumably, this is related to involution of a colloid nodule.
