title: Localization of Tc-99m DTPA in a chordoma.
abstract: The authors report a patient with chordoma that was demonstrated as a photopenic region on Tc-99m MDP bone imaging but that localized Tc-99m DTPA intensely. An explanation for the discrepancy is discussed. Complementary Tc-99m DTPA imaging in the preoperative evaluation of sacral tumors is suggested.
