UNLABELLED
A 3 years old female patient underwent resection and chemotherapy for a yolk sac tumor of the retroperitoneum. Two years later, fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) showed high uptake in the right ischiopubic synchondrosis (IPS), which had a radiolucent structure on CT. The structure showed contrast enhancement on magnetic resonance imaging (MRI), which was a non-specific finding. Six weeks later, a follow-up (18)F-FDG PET/CT scan was performed which showed no abnormal uptake in the IPS. The disappearance of (18)F-FDG uptake preceded that of contrast enhancement on MRI, which was seen 7 months after the initial (18)F-FDG PET/CT scan.
CONCLUSION
This is the first report showing serial changes of (18)F-FDG uptake in IPS, in comparison to MRI findings.
未标注
一名3岁女性患者因腹膜后卵黄囊瘤接受了切除术和化疗。两年后，氟-18氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（(18)F-FDG PET/CT）显示右耻骨坐骨软骨结合部（IPS）摄取增高，该部位在CT上呈透亮结构。该结构在磁共振成像（MRI）上显示有强化，这是一个非特异性表现。六周后，进行了一次随访(18)F-FDG PET/CT扫描，结果显示IPS无异常摄取。(18)F-FDG摄取的消失先于MRI上强化的消失，后者在初次(18)F-FDG PET/CT扫描7个月后出现。
结论
这是第一份展示IPS中(18)F-FDG摄取与MRI表现相比的系列变化的报告。
