Abstract:
We report the 99mTc-MDP bone scan of a 44-year-old man with a history of lung adenocarcinoma and recent multiple joint pain after completing pembrolizumab immunotherapy treatment. This interesting image of symmetric uptakes around bilateral joints throughout the skeleton resembles the ball sensors on a motion capture suit. Hence, we recommend naming this distinctive imaging appearance as the "motion capture suit" sign.
