A 55-year-old female presented with a 10 years history of swelling in the front part of her neck, and a persistent headache for the past 4 months. During the course of her hospital stay, she developed right upper limb monoplegia. An examination showed that she had papillary carcinoma thyroid in an euthyroid state. Further work-up revealed a solitary pulmonary nodule on the left lower lobe, right ventricular tumor thrombus in the heart, and hemorrhagic metastases involving the left cerebral and cerebellar hemispheres. Total thyroidectomy with bilateral functional and central neck dissection was performed. Postoperatively, the patient received radioiodine ablation with I131 for lung and brain metastases, and remnant ablation for primary treatment. She has received regular follow-up care for the past 3 months.
Key words: Papillary carcinoma thyroid, radioiodine ablation, solitary pulmonary nodule, ventricular tumor thrombus
