title: Unusual 131Iodine uptake in a joint demonstrated by SPECT/CT in a patient with differentiated thyroid cancer.
abstract: An 84-year-old woman was referred for radioiodine ablation 2 months after total thyroidectomy for papillary thyroid cancer. Whole-body scan showed an 131Iodine focus in the left hand. 131Iodine uptake persisted after skin decontamination. SPECT/CT revealed focal uptake in the metacarpophalangeal joint of the thumb. Hybrid CT scan and medical history with clinical examination suggested osteoarthritis of the first metacarpophalangeal joint.
