CTICasesNormal Thymic Sestamibi Uptake
Imaging findings
Sestamibi scan shows focal tracer uptake in the upper chest. Chest CT demonstrates normal thymic tissue in this region with no mediastinal mass.
Key takeaways
Normal thymic tissue can demonstrate physiological sestamibi uptake, which can be a false-positive source of uptake and lead to misinterpretation as a parathyroid adenoma or thymoma.
