Female, 72 years old. Reason: Primary HPT. Sestamibi shows Right inferior parathyroid adenoma. RIGHT LOBE MEASUREMENTS: 1.7 x 1.3 x 5.6 cmLEFT LOBE MEASUREMENTS: 4.4 x 2.0 x 1.6 cmISTHMUS MEASUREMENTS: 0.2 cmRIGHT LOBE: Heterogeneous echotexture. A right midpole nodule measures 1.2 x 0.7 x 1.0 cm, spongiform, with echogenic foci suggestive of colloid. LEFT LOBE: Heterogeneous echotexture. A left midpole nodule measures 2.0 x 1.7 x 1.8 cm, solid and heterogeneous, with a hypoechoic rim, scattered calcifications, and internal vascularity. ISTHMUS: Heterogeneous echotexture.PARATHYROID GLANDS: Posterior to the right inferior pole, there is an ovoid hypoechoic nodule measuring 0.5 x 0.6 x 0 .8 cm, with minimal internal vascularity. Posterior to the left inferior pole there is an additional ovoid hypoechoic nodule measuring 0.4 x 0.7 x 0 .9 cm.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Bilateral hypoechoic extrathyroidal nodules posterior to the inferior poles may represent hyperplastic parathyroid glands or parathyroid adenomas.2. A 2 cm solid left thyroid nodule has an appearance suspicious for thyroid carcinoma, particularly papillary type. If not already performed, fine needle aspiration of this lesion is recommended for further evaluation.
