Sialadenitis mimicking metastatic thyroid carcinoma.
In the post-thyroidectomy patient who has received I-131 ablation for thyroid carcinoma, focal uptake on repeat total body images is usually interpreted as being indicative of functioning thyroid metastases. The differential of focal I-131 activity in such a patient has been described. This report adds to the differential by presenting a case of benign sialadenitis that caused focal neck uptake a year after ablation therapy with I-131.
