Thyroid nodules. Hypothyroidism. RIGHT LOBE MEASUREMENTS: 6.0 x 1.6 x 2.4 cm, similar to prior.LEFT LOBE MEASUREMENTS: 4.9 x 1.4 x 1.7 cm, similar to prior.ISTHMUS MEASUREMENTS: 2 mm in AP dimension, similar to prior.RIGHT LOBE: The dominant solid nodule is unchanged in size at 2.4 x 2.2 x 1.5 cm, with minimal cystic change.LEFT LOBE: The poorly circumscribed hypoechoic nodule is unchanged measuring 0.7 x 0.8 x 0.8 cm.ISTHMUS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: Unchanged 15 mm hypoechoic nodule posterior to the left inferior thyroid pole. Not seen on earlier exam 8 mm hypoechoic nodule posterior to the right superior thyroid pole.
1. Multinodular goiter, with unchanged dominant nodules.2. Two hypoechoic nodules posterior to the left and right thyroid lobes, one of which on the right was not seen previously. These may represent parathyroid adenoma/hyperplasia or exophytic thyroid nodules. Correlation with parathyroid function tests may be helpful.
