The patient was a known case of solid variant of papillary carcinoma of thyroid, post three cycles of radioiodine therapy, had reported for a diagnostic 131I-NaI scintigraphy as a part of the workup for planning the next 131I therapy. Clinically, the patient was asymptomatic. 131I-NaI scintigraphy showed an arcuate pattern concentration of tracer in the upper mediastinum, which descended up to the lower mediastinum. A 131I-NaI single photon emission computed tomography\/computed tomography (SPECT\/CT) showed a tracer avid tumor with an extensive tumor thrombus extending from the left brachiocephalic vein to the right ventricle. 18F-fluorodeoxyglucose positron emission tomography\/computed tomography (18F-FDG-PET\/CT) and magnetic resonance imaging (MRI) demonstrated similar findings. The patient was decided to be managed with tyrosine kinase inhibitors as surgical intervention was not deemed possible due to the involvement of major vessels and the high risk of bleeding.<\/jats:p>","DOI":"10.1055\/s-0044-1788737","type":"journal-article","created":{"date-parts":[[2024,8,5]],"date-time":"2024-08-05T23:14:17Z","timestamp":1722899657000},"page":"295-298","source":"Crossref","is-referenced-by-count":2,"title":["A
