Papillary Thyroid Cancer, Small Cell Lung Cancer, and Parathyroid Adenoma Synchronously Visualized on <SUP>99m</SUP>Tc-MIBI SPECT/CT in a Patient With Hyperparathyroidism Comparison With <SUP>18</SUP>F-FDG PET/CT

초록

Tc-99m-MIBI scintigraphy is a nuclear medicine imaging modality commonly used for the preoperative localization of parathyroid adenomas in patients with hyperparathyroidism. In addition, Tc-99m-MIBI can also be used for imaging various tumors due to its unique mechanism of intracellular accumulation. Here, we introduced a case of a single Tc-99m-MIBI SPECT/CT simultaneously visualized two different malignant tumors, such as papillary thyroid cancer and small cell lung cancer, along with a parathyroid adenoma in a patient with hyperparathyroidism. The clinical usefulness of Tc-99m-MIBI SPECT/CT was also explored by comparing it with 18F-FDG PET/CT among the three tumors.
