Reason: HPT. Assess for parathyroid adenoma. History of thyroid nodule that was biopsied in the past. RIGHT LOBE MEASUREMENTS: 4.0 x 1.4 x 0.7 cmLEFT LOBE MEASUREMENTS: 3.9 x 1.2 x 1.3 cm.ISTHMUS MEASUREMENTS: 0.3 cm.RIGHT LOBE: Diffusely heterogeneous thyroid gland. No discrete nodules or masses.LEFT LOBE: Diffusely heterogeneous thyroid gland. Exophytic lesion in the inferior aspect of the left thyroid lobe measures 0.8 x 0.7 x 0.9 cm likely represents a benign colloid nodule.ISTHMUS: Diffusely heterogeneous thyroid gland. No discrete nodules or masses.PARATHYROID GLANDS: Well-defined hypoechoic extrathyroidal lesion projecting inferiorly to the right thyroid lobe measures 0.5 x 0.5 x 0.3 cm and is favored to represent suspected parathyroid adenoma.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
Extrathyroidal lesion projecting inferior to the right thyroid lobe is consistent with a parathyroid adenoma candidate.Heterogeneous thyroid gland suggestive of chronic thyroiditis.
