Thyroid nodules in the elderly are more frequent and more frequently m
alignant. Fine needle aspiration is the first step to diagnose these t
ype of nodules, and thyroid scans and ultrasounds may be obtained in s
pecial cases. Thyroid suppression is frequently not effective in decre
asing the size of the nodule and may cause subclinical or clinical thy
rotoxicosis. It is not uncommon to discover that what initially was th
ought to be a solitary nodule is only the dominant nodule of a multino
dular goiter.
