title: Unexpectedly expected fetal thyroid function on posttreated radioiodine (131I) SPECT/CT of a patient with differentiated thyroid cancer.
abstract: We present a 25-year-old woman who has a diagnosis of differentiated thyroid cancer, a 2.5-cm papillary carcinoma in the right lobe, and presence of minimal extrathyroid invasion. 131I ablation and/or treatment of 150 mCi was given orally 3 months after total thyroidectomy. A fetus with radioiodine uptake in the fetal thyroid was unsuspectedly detected by SPECT/CT after 131I treatment.
