Hypoechoic focus projecting inferior and posterior to the atrophic right thyroid gland; while this may represent a parathyroid adenoma candidate, it is unclear whether this may represent a thyroid nodule arising from the atrophic gland. Similarly, there is a hypoechoic lesion arising from the posterior aspect of the mid atrophic right thyroid gland which may represent a thyroid nodule or parathyroid adenoma candidate. Correlation with nuclear medicine scan recommended.
