Diffuse pulmonary metastases with negative 18FDG positron emission tomography/computed tomography and positive post-radioiodine therapy scan of papillary thyroid cancer

摘要

A female papillary thyroid cancer patient with diffuse micronodular pulmonary metastases was confirmed only by post radioactive iodine (RAI) therapy whole body scan (RxWBS).Her diagnostic iodine-131 whole body scan (DxWBS),chestCT and 18FDG PET/CT scan were all negative.Attention and pitfalls of this case concerning surgical and RAI dosemanagement are against current international guidelines on thyroid cancer.
