Radionuclide imaging in extraskeletal myxoid chondrosarcoma.
The authors present a case of extraskeletal myxoid chondrosarcoma. The MR study clearly showed the extent of the tumor and a "rings and arcs" pattern appeared after Gadolinium-DTPA administration in the T1 weighted images. Dynamic Tc-99m MDP and Tc-99m DTPA scintigraphy showed increased blood flow in the mass. The delayed 3-hour images demonstrated moderate Tc-99m MDP uptake, but intense Tc-99m DTPA accumulation in the tumor. Surprisingly, the Ga-67 scan failed to demonstrate the tumor.
