摘要：
一名右脚踝患有尤文肉瘤的 29 岁男性接受了 68Ga-DOTA-IBA PET/CT 和 18F-FDG PET/CT，两者均显示原发肿瘤具有高放射性示踪剂活性。有趣的是，使用 68Ga-DOTA-IBA PET/CT 检测第六胸椎，使用 18F-FDG PET/CT 检测双侧肱骨，早期发现骨转移。在尤文肉瘤的原发部位和转移部位均发现 68Ga-DOTA-IBA 的摄取较高。 177Lu-DOTA-IBA 可能是治疗转移性或复发性尤文肉瘤的可能疗法之一。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。
A 29-year-old man with Ewing sarcoma in the right ankle underwent 68Ga-DOTA-IBA PET/CT and 18F-FDG PET/CT, both of which showed high radiotracer activity for the primary tumor. Interestingly, bone metastases were detected early using 68Ga-DOTA-IBA PET/CT for the sixth thoracic vertebrae and with 18F-FDG PET/CT for the bilateral humerus. Higher uptake of 68Ga-DOTA-IBA was found in both primary and metastatic sites of Ewing sarcoma. 177Lu-DOTA-IBA may be one of the possible therapies for metastatic or recurrent Ewing sarcoma.Copyright © 2024 Wolters Kluwer Health, Inc.
