case_images: We report a case of a 58-year-old female presented to our center with a voluminous thyroid nodule overall size of 40 x 33 x 26 mm (volume of 17.9 ml), occupying almost the entire left thyroid lobe (Figure 1).
case_images: Thyroid technetium 99m scintigraphy showing hyperactive nodule on the left lobe and full suppression in the remainder of the gland.

case_images: These autoantibodies were undetectable and we ruled out the diagnosis of Graves' disease and hashitoxicosis. The lack of neck pain and the normality of acute inflammation parameters (erythrocyte sedimentation rate (ESR) and PCR) allowed us to exclude the diagnosis of subacute thyroiditis. The patient was therefore submitted to thyroid scintigraphy which showed a left nodule under complete functional autonomy, corresponding to the nodule treated with PEI (Figure 2).
