55-year-old female patient with history of hyperparathyroidism. Evaluate thyroid nodule size, location, and any abnormal lymph nodes. RIGHT LOBE MEASUREMENTS: 7.2 x 3.1 x 2.2 cm.LEFT LOBE MEASUREMENTS: 4.7 x 1.6 x 1.4 cm.ISTHMUS MEASUREMENTS: 6 mm in thickness.RIGHT LOBE: The right thyroid lobe contains multiple nodules with the largest complex cystic nodule measuring 2.4 x 1.1 x 2.0 cm in the lower pole. Either within or extrathyroidal and posterior to the lower pole there is a 2.2 x 1.7 x 2.5 cm hypoechoic, solid nodule that demonstrates internal vascularity.LEFT LOBE: The left thyroid lobe contains scattered cystic nodules and a dominant 1.8 x 1.1 x 1.4 cm solid nodule with a central cyst.ISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: Either within or extrathyroidal and posterior to the right lower pole there is a 2.2 x 1.7 x 2.5 cm hypoechoic, solid nodule that demonstrates internal vascularity. There is a solid, hypoechoic nodule measuring 0.9 x 1.0 x 1.7 cm medial to the inferior pole of the left thyroid lobe may represent a parathyroid adenoma.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Solid, hypoechoic nodule which is either extrathyroidal and posterior to the right lower pole or within in. If this is extrathyroidal, a parathyroid adenoma is favored; correlate with nuclear medicine scan. If this does not correlate to a parathyroid adenoma on nuclear medicine scan and/or is intrathyroidal in location, then biopsy is recommended for further evaluation.2. Extrathyroid hypoechoic nodule medial to the left lower pole may represent a parathyroid adenoma.3. Bilateral thyroid nodules as described above.
