86-year-old female with hyperparathyroidism. RIGHT LOBE MEASUREMENTS: The right thyroid lobe measures 5.7 x 2.1 x 2 cm.LEFT LOBE MEASUREMENTS: The left thyroid lobe measures 7.1 x 2.6 x 3.5 cm.ISTHMUS MEASUREMENTS: The isthmus measures 2.1 cm in thickness.RIGHT LOBE: Multinodular appearance. Partially cystic nodule with eccentric solid component of the right lower pole measuring 1.7 x 1.1 x 1.2 cm, and the solid portion of this nodule measures 1 x 0.7 x 0.7 cm.LEFT LOBE: Multinodular appearance. Heterogeneity of the enlarged left thyroid lobe limits visualization for accurate measurement of discrete nodules.ISTHMUS: Heterogenous predominantly hyperechoic nodule of the thyroid isthmus measuring 2.1 x 3.2 x 2.3 cm.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Multinodular thyroid goiter. The measured nodules of the thyroid isthmus and right lower pole demonstrate characteristics most compatible with "low suspicion" nodules per ATA criteria. These nodules are amenable to percutaneous biopsy as clinically recommended.2. No definite candidates for a parathyroid adenoma. Please refer to the same day nuclear medicine exam for more details.
