A 47-year-old woman was diagnosed as papillary thyroid carcinoma. I-131 ablation therapy was applied following total thyroidectomy, and the whole-body scan revealed a focus of increased uptake in the right upper quadrant. Lateral view images of the uptake site showed that the focus was located near the right liver lobe. The patient was referred to radiology department for correlative abdominal Computed Tomography (CT) and Ultrasonography (US) to rule out a possible liver metastasis. CT images detected a gallstone in the corresponding area, which was verified by US. These methods did not reveal any metastatic disease in the liver or in other abdominal organs. This is the first published case report documents a rare false-positive finding of I-131 scan that was associated with an asymptomatic gallstone, and emphasizes the importance of correlative imaging in gallbladder related I-131 uptake.
一名47岁女性被诊断为甲状腺乳头状癌。全甲状腺切除术后进行了I-131消融治疗，全身扫描显示右上象限有一个摄取增加的病灶。摄取部位的侧位图像显示病灶位于右肝叶附近。患者被转诊至放射科进行相关腹部计算机断层扫描（CT）和超声检查（US），以排除可能的肝转移。CT图像在相应区域检测到一枚胆结石，超声检查证实了这一结果。这些检查方法未发现肝脏或其他腹部器官有任何转移性疾病。这是首次发表的病例报告，记录了与无症状胆结石相关的I-131扫描罕见假阳性发现，并强调了胆囊相关I-131摄取中相关成像的重要性。
