一名 41 岁女性因右颌下肿胀 2 个月病史就诊。活检显示神经母细胞瘤（NB）。患者被转诊进行分期 PET/CT 扫描。我们比较了 18F-DOPA PET/CT 和 18F-FDG PET/CT 扫描的结果。患者的两种影像学检查结果均呈阳性；然而，18F-FDG PET/CT 的肿瘤勾画效果更佳。肿瘤对FDG的摄取显着高于肿瘤对DOPA的摄取。术后随访 FDG PET/CT 扫描显示局部复发 NB 及其转移灶大量浓缩 FDG。我们介绍了一个非常罕见的成人颈部 NB 病例，使用 FDG 而不是 DOPA PET/CT 可以更好地成像。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。

A 41-year-old woman presented with 2 months history of right submandibular swelling. Biopsy revealed neuroblastoma (NB). Patient was referred for staging PET/CT scan. We compared the findings of 18F-DOPA PET/CT and 18F-FDG PET/CT scans. Both imaging modalities were positive in the patient; however, tumor delineation was superior with 18F-FDG PET/CT. Tumor uptake of FDG was significantly higher than tumor uptake of DOPA. Follow-up FDG PET/CT scan postsurgery showed local recurrent NB and their metastases avidly concentrate FDG. We present a very rare case of adult NB of the neck better imaged with FDG instead of DOPA PET/CT.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
