Here we describe an abnormal uptake in the hepatic region on postablative 131I scintigraphy in a 37-year-old woman with papillary thyroid cancer. The SPECT/CT images revealed this “hepatic activity” corresponded to gallbladder stone. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
