A 17-year-old female had been complaining of a headache for 6 years. She presented severe hypertension (200/138 mmHg) on admission. CT showed a hypervascular tumor behind the urinary bladder and a swelling of the right internal obturator node. Intense FDG uptakes were identified in the both lesions. High FDG accumulation was also observed in the brown adipose tissue (BAT) throughout the patient's body, and intense contrast enhancement was found in the BAT on CT. The diagnosis was a malignant paraganglioma with obturator node metastasis. The post-surgery FDG-PET/ CT examination revealed that the FDG accumulations in the BAT had completely disappeared.
一名17岁女性主诉头痛6年。入院时出现严重高血压（200/138 mmHg）。CT显示膀胱后方有一个富血管肿瘤，右侧闭孔淋巴结肿大。两个病灶均发现有强烈的FDG摄取。在患者全身的棕色脂肪组织（BAT）中也观察到高FDG积聚，CT上BAT有强烈的对比增强。诊断为伴有闭孔淋巴结转移的恶性副神经节瘤。术后FDG-PET/CT检查显示BAT中的FDG积聚已完全消失。
