53-year-old woman with history of Graves' disease, now with new onset goiter. RIGHT LOBE MEASUREMENTS: 3.1 x 3.5 x 7 cm. The right thyroid lobe is enlarged with rounded contours.LEFT LOBE MEASUREMENTS: 2.1 x 2.6 x 6.9 cm. The left thyroid lobe is enlarged with round contours.ISTHMUS MEASUREMENTS: The isthmus measures 0.4 cm in AP diameter.RIGHT LOBE: There is heterogeneous echogenicity throughout the right thyroid lobe with a number of small, homogenously hyperechoic nodules scattered throughout the thyroid parenchyma. Additionally, there is diffusely increased vascularity. For reference, an echogenic nodule in the posterior, upper right lobe measures 0.8 x 0.9 x 1.3 cm.LEFT LOBE: There is heterogeneous echogenicity throughout the left thyroid lobe with a number of small, homogenously hyperechoic nodules scattered throughout the thyroid parenchyma. Additionally, there is diffusely increased vascularity. A 2.1 x 1.1 x 1.0 cm focus of slightly nodular tissue of similar echogenicity to the remaining thyroid gland is seen immediately posterior to the inferior pole of the thyroid lobe.ISTHMUS: Heterogeneous echogenicity. Ovoid iso to minimally hyperechoic nodule measuring 0.6 x 1.2 x 1.4 cm.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Acute thyroiditis. Multiple echogenic nodules have been described in thyroiditis.2.Thyroid nodules as measured.3.Nodular region posterior to the inferior pole of the left thyroid lobe. This is most suggestive of exophytic thyroid nodule by echotexture, less likely to be a parathyroid adenoma or lymphadenopathy.
