History of recurrent hyperparathyroidism. In the mid to superior pole of the right thyroid lobe, there is an enhancing nodule measuring 1.0 x 0.9 cm, correlating with enhancing abnormality seen on the prior MRI study. The lesion also correlates with abnormal uptake in the prior nuclear parathyroid study, and therefore suggests it most likely represents a parathyroid adenoma. More inferiorly and medially in the right thyroid lobe, there are two additional hypodense lesions with the larger one measuring 0.9 x 0 .7 cm, which has nonspecific imaging appearance, but may represent colloid cysts. There are tiny nodular densities in the visceral space around the thyroid glands, and in the superior mediastinum, which may represent small lymph nodes.There is mild atelectasis in the lungs. There is mild degenerative disease of the cervical spine, with minimal anterolisthesis at C4 over C5 and disc space narrowing at C5 - C6 level.
1. Enhancing nodule in right thyroid lobe, correlating with previous studies, suggesting it likely represents a parathyroid adenoma. 2. No other suspicious nodules in the neck.
