17-year-old female with hypothyroidism transferring care to University of Chicago.EXAMINATION: Sonogram thyroid 12/21/2016 RIGHT LOBE MEASUREMENTS: 4.9 x 1.5 x 1.3 cmLEFT LOBE MEASUREMENTS: 4.1 x 1.1 x 1.0 cmISTHMUS MEASUREMENTS: 0.3 cmRIGHT LOBE: Two predominantly hypoechoic lesions are visualized of which neither demonstrate calcification. The first is non-vascular and measures 0.5 x 0.4 x 0.5 and may be extrathyroid in location. The second lesion is hyperechoic centrally and demonstrates central vascularity and measures 0.9 x 0.3 x 0.7 cm. Background glandular heterogeneity and somewhat ill-defined areas of hyperechogenicity.LEFT LOBE: A round mildly hypoechoic mass is seen posteriorly with medial extension measuring 1.4 x 0.5 x 0.5 cm. There is mild peripheral vascularity. Background glandular heterogeneity and somewhat ill-defined areas of hyperechogenicity.ISTHMUS: Background glandular heterogeneity and somewhat ill-defined areas of hyper echogenicity.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Predominantly hypoechoic lesion within the right lobe of the thyroid may be extrathyroidal in location. Correlation with prior outside imaging is recommended to assess for change.2. The second right thyroid lesion appears morphologically compatible with lymph node.3. Hypoechoic mass within the left thyroid is of unclear etiology, but could represent a parathyroid gland. Correlation with serum calcium and PTH levels may be obtained.
