Increased Concentration of99mTc-Methylene Diphosphonate and67Ga-Citrate in Extracranial Bone Metastases from Pinealoma

摘要

A rare case of extracranial bone metastases from pinealoma is reported.99mTc-methylene diphosphonate and67Ga-citrate scans were of great clinical value in confirming the presence of bone metastases. Bone lesions were positively delineated by both radionuclides, but the concentration of67Ga-citrate was more extensive than that of99mTc-methylene diphosphonate.
