thyroid hemiagenesis on the basis of these findings. Tc-99m pertechnetate thyroid scintigraphy ( Fig. 3 ) showed uptake in the upper part of the neck and the center of the oral cavity, without uptake in the normal position of the thyroid or other positions

irregular hypoechoic region in the right lobe and posterior attenuation of echogenicity ( Fig. 1 ). The thyroid uptake value on technetium-99m scintigraphy was near the lower limit of the normal range ( Fig. 2 ). Thus, his condition at that time was

( Fig. 1 ). Figure 1 Technetium-99m scintigraphy scan of the thyroid gland. The radiotracer uptake is diffusely decreased throughout both lobes of the thyroid gland with overall thyroid uptake significantly less than background salivary gland uptake

an oscillation of thyroid function. One possible explanation is that the scintigraphy was done in a transition phase between hypo- and hyper-thyroidism, once TSH decreased significantly within 3 days and TRAbs were elevated. This fact may lead to an

Background Oncocytic thyroid neoplasms are a variant of follicular tumors composed of distinctive large acidophilic cells (Hürthle cells). Just like other types of well-differentiated follicular thyroid tumors, oncocytic neoplasms can be

scintigraphy with 99m Tc-pertechnetate confirmed a small warm nodule in the lower part of right thyroid lobe, corresponding to the nodule on ultrasonography ( Fig. 1 ). Figure 1 Thyroid scan with 99m Tc-pertechnetate (with permission from V. Rouskova
