Dual Autonomously Functioning Thyroid Nodule: An Unusual Imaging Finding.

Abstract

A 48-year-old female, a known case of ulcerative colitis, on routine workup, was incidentally detected to have biochemical hyperthyroidism. ^99mTc pertechnetate thyroid scintigraphy performed for the evaluation of hyperthyroidism revealed two foci of increased tracer uptake in the right thyroid lobe with suppressed uptake in the rest of the thyroid gland consistent with dual autonomously functioning thyroid nodules.
