Abstract

Papillary carcinoma of thyroid tends to be indolent. This is an unusual case of papillary carcinoma of thyroid with asymptomatic pulmonary metastasis for more than a decade, finally presenting with mild respiratory symptoms in a 21-year-old female. Fine needle aspiration and cytology (FNA-C) of a nodule in the lungs revealed features consistent with a papillary carcinoma of thyroid. Confirmed on thyroidectomy specimen. She subsequently received Iodine-131 (I131). A follow-up radio-iodide scan, 48 hours after, revealed diffuse uptake within the lung parenchyma. With static nodular shadowing on radiograph, a metastatic origin, in particular that of the thyroid, should be considered. I131 scintigraphy can help support the diagnosis of carcinoma of thyroid.
