[Iodine uptake in the chest in the follow-up of well-differentiated thyroid cancer].
Differentiated thyroid cancer is a disease having a very good prognosis when treated adequately. Ablation treatment with (131)I is frequently adjunct to surgery in these patients since it improves survival. Radioiodine whole-body scan is one of the imaging modality of choice in the follow-up of patients with this kind of pathology. After ablation treatment of the thyroid gland, any radioiodine accumulation in a non-physiological location usually means the presence of functioning metastasis. Recognition of potential false-positives is essential to avoid unnecessary exposure to further radiation from repeated therapeutic doses of radioactive iodine. We report a case of uptake in the chest due to bronchiectasis, potentially masquerading as pulmonary metastasis.
