Ovarian Teratoma Mimicking Metastasis on I-131 Scan : A Case Report

Abstract

The whole body I-131 scan is routinely performed in the postoperative treatment of patients with well-differentiated thyroid cancer. Accurate interpretation of whole body I-131 scan after thyroidectomy is critical to appropriate management of patients with thyroid cancer, to prevent unnecessary surgical removal or exposure to radioiodine. Unfortunately, false-positive uptakes in several other organs and their associated disease processes have been reported. We report a case of false-positive iodine uptake in the pelvic region with incidentally diagnosed mature cystic teratoma.
