Solitary Osteogenic Sternum Plasmacytoma on Bone Scintigraphy and FDG PET/CT
We reported a rare solitary osteogenic sternum plasmacytoma case. A 49-year-old woman experienced progressing pain in the sternum for 2 years. Abnormal 99mTc-MDP accumulation and increase in 18F-FDG uptake (SUVmax, 4.4) were co-localized with the osteogenic lesion in the sternum body detected by diagnostic CT. The lesion was histologically confirmed as plasma cell neoplasm suggestive of plasmacytoma. The patient had good response to radiotherapy.
