58-year-old male patient with tertiary hyperparathyroidism status post two parathyroidectomies with persistent HPT. Sestamibi scan shows left inferior uptake. Evaluate for thyroid nodule size and location and parathyroid adenomas. RIGHT LOBE MEASUREMENTS: 4.7 x 3.1 x 3.4 cm.LEFT LOBE MEASUREMENTS: 4.2 x 1.9 x 2.6 cm.ISTHMUS MEASUREMENTS: 7 mm in thickness.RIGHT LOBE: The right thyroid lobe is heterogeneous in echogenicity and contains a 0.8 x 0.6 x 0.6 cm hypoechoic nodule within the left inferior pole.LEFT LOBE: The left thyroid lobe is heterogeneous in echogenicity without dominant thyroid lesion.ISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: There is a 0.5 x 0.5 x 9 mm hypoechoic nodule inferior to the left inferior pole, which may correlate to a parathyroid adenoma.LYMPH NODES: A right level three lymph node measures 1.4 x 0.7 x 1.1 cm.OTHER: No significant abnormality noted.
1. No dominant thyroid lesion identified.2. Possible parathyroid adenoma correlate inferior to the left thyroid lobe.
