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.
脊索瘤是一种起源于脊索残余组织的恶性肿瘤，是骶骨最常见的原发性肿瘤。虽然大多数骶骨肿瘤显示亲骨性放射性药物浓度增加，但脊索瘤通常表现为摄取减少。作者展示了一幅骶尾部脊索瘤的影像，在平面和单光子发射计算机断层扫描/计算机断层扫描骨闪烁显像上有骨质溶解且99m锝亚甲基二膦酸盐摄取增加。
