Abstract

Hemithyroiditis is a rare form of thyroid inflammation characterized by involvement of only one lobe of thyroid
gland. The exact pathophysiological mechanism remains unclear; however, it is thought to represent a localized
manifestation of chronic thyroiditis that may be triggered by upper respiratory tract infections, trauma and
radiation exposure. It has a preponderance for middle aged women. Normally, most thyroiditis conditions (like
Hashimoto’s or subacute thyroiditis) involve both lobes, but occasionally inflammation is confined to one side. We
report a case of hemithyroiditis identified on a 99m-Tc pertechnetate thyroid scan, highlighting the importance of
imaging in recognizing this uncommon presentation.
