Malignant struma ovarii is a rare disease in gynecology and the optimal treatment regimen for the tumor remains obscure. We present a patient who had malignant struma ovarii with peritoneal implants and pelvic structures and liver metastases shown on posttreatment iodine I-131 single-photon emission tomography (SPECT) and low-dose computed tomography (CT). The roles of I-131 ablation in the management of the disease are reviewed and discussed.
