What size was: the nodule on ultrasound? Small nodules may not be detectable on the nuclear scan, and the scan will look normal.

Do not worry: The ultrasound study probably showed one or more nodular structures within the thyroid gland. These are mostly benign nodules, but a few are malignant. In the nuclear study, benign nodules take up the activity similar to normal thyroid tissue, and malignant do not, resulting in a cold area relative to the remainder of the gland. Apparently, you did not have a cold nodule. You only need watching.
