Bone scintigraphy with Tc-99m HMDP and gallium scintigraphy were evaluated in four patients with a primary sacrococcygeal chordoma. All lesions showed a photon-deficient or cold lesion corresponding to the tumor on bone scintigraphy, with no abnormal accumulation clearly observed on gallium scintigraphy. These findings led the authors to conclude that a midline sacrococcygeal tumor showing reduced uptake or a cold lesion on bone scintigraphy and no increased accumulation on gallium scintigraphy could be a chordoma rather than the malignant neoplasm suspected in this region.
对4例原发性骶尾部脊索瘤患者进行了99m锝-亚甲基二膦酸盐骨闪烁显像和镓闪烁显像评估。所有病变在骨闪烁显像上均显示对应于肿瘤的光子缺乏或冷区病变，在镓闪烁显像上未观察到明显异常聚集。这些发现使作者得出结论，在骨闪烁显像上显示摄取减少或冷区病变且在镓闪烁显像上无聚集增加的中线骶尾部肿瘤可能是脊索瘤，而非该区域疑似的恶性肿瘤。
