== Study Questions ==
* <spoiler text="What is the likelihood that this tumor would have been 'hot' or would have taken up radioactive iodine?">Benign tumors are more likely to take up radioactive iodine than malignant tumors.</spoiler>
* <spoiler text="What are the differential diagnoses for thyroid masses?">Goiter, adenomas, neoplastic tumors of the thyroid.</spoiler>
* <spoiler text="Although usually asymptomatic, what important clinical problems can occur in patients with benign thyroid adenomas?">They may:
# increase in size and cause pressure symptoms in the neck,
# achieve a certain size and then plateau,
# suddenly enlarge and become painful owing to intralesional hemorrhage, and
# rarely synthesize T3 or T4 and cause hyperthyroidism that is usually mild and unassociated with ophthalmopathy.</spoiler>
* <spoiler text="Is someone with a thyroid adenoma at risk for thyroid carcinoma?">No. The risk of malignant transformation is almost negligible.</spoiler>
