Meningiomas constitute 37% of primary central nervous system tumors and are more common in women. Also may occur with other primary malignancies, which can cause confusion with the metastasis in whole body bone scan (WBBS) imaging. A 58-year-old woman diagnosed with breast cancer was referred to the WBBS for the investigation of possible bone metastases. In the planar images, radiotracer uptake at multiple sites was detected on the anterior side of the skull base and the posterior side of the vertex of the cranium. Single photon emission computed tomography/computed tomography was performed for anatomical localization of possible metastatic lesions, and it revealed that detected accumulations of radiotracer did not belong to the bone metastases; uptakes were located at the cerebral parenchyma and the lesions in the falx cerebri. Patient history explained that she had been diagnosed with meningioma five years ago, which mimicked bone metastases in this study.
脑膜瘤占原发性中枢神经系统肿瘤的37%，在女性中更为常见。它也可能与其他原发性恶性肿瘤同时发生，这可能会在全身骨扫描（WBBS）成像中导致与转移瘤混淆。一名58岁被诊断为乳腺癌的女性被转诊至WBBS以检查是否可能存在骨转移。在平面图像中，在颅底前侧和颅顶后侧的多个部位检测到放射性示踪剂摄取。对可能的转移瘤进行了解剖定位的单光子发射计算机断层扫描/计算机断层扫描，结果显示检测到的放射性示踪剂积聚并不属于骨转移；摄取位于脑实质和大脑镰病变处。患者病史表明她五年前被诊断出患有脑膜瘤，在本研究中其表现类似于骨转移。
