Incidental thyroid 99mTc-MDP uptake in a patient affected by differentiated thyroid cancer.
We report a case of incidental uptake of 99mTc-methylene diphosphonate in the thyroid in a 62-year-old female with a history of breast cancer treated with quadrantectomy, chemotherapy and radiotherapy, who underwent total-body-bone scintigraphy during follow up. Planar scintigraphy was followed by neck SPECT-CT that demonstrated an area of increased tracer uptake in the neck at the left lobe of the thyroid. Neck ultrasonography showed a nodule corresponding to SPECT-CT finding and the ultrasound-guided fine needle aspiration documented the presence of papillary carcinoma. The patient underwent total thyroidectomy and ipsilateral lymphadenectomy; histological examination confirmed the presence of a papillary carcinoma and the patient underwent ablation therapy with iodine-131.
