Abstract

A patient, a female in her 70s, underwent total thyroidectomy for thyroid carcinoma and was referred to our hospital seven months later for Iodine-131 (I-131) therapy to ablate the remaining thyroid tissue. The patient received 2.55 GBq of I-131 and single photon emission computed tomography/computed tomography was performed on Day 11. This revealed irregular and heterogeneous abnormal uptake in the pelvis. Ultrasonography revealed no abnormalities in the uterus, but a multilocular mass measuring approximately 12 cm was found in the left ovary. Blood tests revealed an elevated carbohydrate antigen 19-9 level of 13.7 U/mL. The patient underwent simple abdominal total hysterectomy, bilateral adnexectomy, and partial omentectomy. Histopathological examination confirmed a diagnosis of ovarian mucinous borderline tumor. No thyroid tissue was detected.
