title: Sacrococcygeal chordoma: Increased (99m)Tc methylene diphosphonate uptake on single photon emission computed tomography/computed tomography bone scintigraphy.
abstract: Chordoma is a malignant tumor arising from the remnants of the notochord, and is the most frequent primitive tumor of the sacrum. While most sacral tumors show increased concentration of bone-seeking radiopharmaceuticals, chordomas usually exhibit decreased uptake. The authors present an image of a sacrococcygeal chordoma with osteolysis and increased uptake of 99mTc methylene diphosphonate on planar and single photon emission computed tomography/computed tomography bone scintigraphy.
