Özet

Nasolacrimal duct obstruction (NLDO) is a rare complication after radioiodine therapy and may cause false positive I-131 uptake at the point of obstruction in I-131 whole body scan. Here, we report a 59-year-old female patient with papillary thyroid cancer treated with total thyroidectomy followed by I-131 therapy. I-131 whole body scan revealed focal uptake in the head. Single photon emission computed tomography/computed tomography (CT) showed focal uptake at the right proximal nasolacrimal duct. The ophthalmologic examination and the diagnostic maxillofacial CT confirmed the diagnosis of NLDO.
