History of hyperparathyroidism. RIGHT LOBE MEASUREMENTS: 6.3 x 2.2 x 2.2 cmLEFT LOBE MEASUREMENTS: 6.5 x 2.5 x 2.0 cmISTHMUS MEASUREMENTS: 6 mmRIGHT LOBE: The right thyroid lobe is homogeneous and normal in echogenicity without a discrete nodule.LEFT LOBE: The left thyroid lobe is homogeneous and normal in echogenicity without a discrete noduleISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: Immediately inferior to the left thyroid lobe is a 1.4 x 0.9 x 1.0 cm hypoechoic nodule without significant hypervascularity.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.4 cm hypoechoic nodule immediately inferior to the left thyroid lobe may represent a parathyroid adenoma. Correlate with nuclear medicine study.
