PET/CT scan was performed in a 43-year-old woman to evaluate pulmonary nodules/masses. The images showed that there was only minimal FDG activity in the masses. However, these soft tissue masses in the lungs had significantly elevated 99mTc 3PRGD2 activity. Pathological examination demonstrated that this patient suffered benign metastasizing leiomyoma.
