摘　　要：目前公认的分化型甲状腺癌治疗方法是手术联合131I治疗以及甲状腺素抑制治疗。131I治疗前常规行诊断性131I全身显像检查,以了解患者残余甲状腺及远处转移情况。但是,131I全身显像常有各种假阳性摄取干扰诊断以及需要治疗计划的制定。此文展示了一个罕见病例,在分化型甲状腺癌患者131I全身显像中表现为阳性摄取,病理结果为成熟型畸胎瘤。Total or near total thyroidectomy combined with the radioactive 131I(RAI)therapy is recognized as an initial treatment modality in differentiated thyroid carcinoma(DTC)patients.Whole body 131I scan(WBS)is routinely performed before RAI,which is an effective mean for depicting residual thyroid tissues and distant metastases.An accurate interpretation of positive uptakes on pre-therapy whole body I-131 scan images is important to make an appropriate treatment plan for patients.Unfortunately,there are many false positive uptake lesions,which are difficult to diagnose and easy to be misdiagnosed.In the current study,we present a rare case with radioiodine uptake in the pelvic region and is finally diagnosed as mature cystic ovarian teratoma by pathology.
