Various etiologies could cause focal 131I accumulation. Hepatic cyst is one of these etiologies. Here we present a 59-year-old man with a history of papillary thyroid cancer resection who received radioiodine therapy for three times. The images after the 131I therapy of the second and third time showed variable activity uptake in the same hepatic cysts.
