title: Tc-99m DTPA uptake in extramedullary plasmacytoma of the retroperitoneum.
abstract: A case is presented in which uptake of Tc-99m DTPA has been demonstrated in an extramedullary plasmacytoma of the retroperitoneum. Because Ga-67 citrate does not concentrate in the same areas as Tc-99m DTPA, a radionuclide-specific uptake mechanism may be present. Extramedullary plasmacytoma should be included in the list of possible causes if extrarenal or extracentral nervous system uptake of Tc-99m DTPA occurs.
