Inflammatory diseases of the lung causing false-positive 131iodine whole body scans in the evaluation of papillary thyroid carcinoma. Two case reports.
The 131I whole body scan is commonly used to establish the presence of metastatic disease in papillary thyroid carcinoma. False-positive scans are rare, but have been reported. We present two cases of aberrant uptake of radioiodine after thyroidectomy and 131I ablation due to inflammatory conditions of the lung, aspergilloma, and respiratory bronchiolitis.
