Incidentally Detected Thyroid Follicular Adenoma on Myocardial Perfusion Scintigraphy with Tc-99m MIBI
Technetium-99m sestamibi (Tc-99m MIBI) is a routinely used radiopharmaceutical for myocardial perfusion scintigraphy (MPS). Here, we present a case of a 76-year-old woman with mild transient chest pain but normal laboratory examination results who underwent Tc-99m sestamibi (MIBI) myocardial perfusion imaging, and an abnormal focal radionuclide uptake in the left lobe of the thyroid gland was detected. After that, the patient underwent left hemithyroidectomy, and the result of the pathology came out as follicular adenoma. In this case, we wanted to discuss the significance of MIBI uptake in thyroid nodules and discuss the importance of evaluating raw data images for the detection of noncardiac pathologies in myocardial perfusion scintigraphy.
