29-year-old female with history of multinodular goiter.Three dominant nodules. Please evaluate for interval changes. RIGHT LOBE MEASUREMENTS: The right thyroid lobe measures 5.7 x 1.8 x 2.3 cm.LEFT LOBE MEASUREMENTS: The left thyroid lobe measures 6.4 x 3.7 x 4.8 cm.ISTHMUS MEASUREMENTS: The thyroid isthmus measures 0.4 cm in thickness.RIGHT LOBE: The right thyroid lobe has heterogenous echotexture. The dominant nodule of the right lower lobe measures 1.9 x 1 x 0.9 cm (prior 1.6 x 1 x 0.8).LEFT LOBE: Enlarged left thyroid lobe containing multiple solid/cystic nodules. The known dominant nodule of the left upper pole measures 4.9 x 2.7 x 3.8 cm (prior 4.6 x 3.5 x 2.4 cm).ISTHMUS: The heterogenous solid/cystic nodule of the isthmus measures 2.4 x 2.6 x 1.4 cm (prior 2.1 x 2 x 1.4 cm).PARATHYROID GLANDS: A hypoechoic focus posterior-inferior to the right thyroid lobe measures 1.3 x 0.8 x 0.7 cm.LYMPH NODES: No suspicious cervical lymphadenopathy.OTHER: No significant abnormality noted.
1. Thyromegaly with multiple solid/cystic nodules. These nodules are similar in appearance and stable to slightly increased in size.2. A hypoechoic focus posterior-inferior to the right thyroid lobe is a candidate for parathyroid tissue. Correlation with nuclear medicine imaging is suggested.
