Primary hyperparathyroidism. RIGHT LOBE MEASUREMENTS: 4.0 x 1.2 x 1.1 cmLEFT LOBE MEASUREMENTS: 4.0 x 1.0 x 1.2 cmISTHMUS MEASUREMENTS: No significant abnormality noted.RIGHT LOBE: Normal echogenicity without a discrete nodule.LEFT LOBE: Normal echogenicity without a discrete nodule.ISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: Immediately dorsal to the mid/lower portion of the right thyroid lobe is a 1.2 x 0.4 x 0.7 cm hypoechoic nodule.LYMPH NODES: No pathologically enlarged or morphologically suspicious appearing cervical lymph nodes.OTHER: No significant abnormality noted.
1.2 x 0.4 x 0.7 cm hypoechoic nodule dorsal to the mid/lower portion of the right thyroid lobe may represent a parathyroid adenoma in the appropriate clinical setting. Correlate with same day nuclear medicine study.
