We present 4 cases of patients who underwent F-fluciclovine PET for prostate cancer demonstrating physiologic uptake in the celiac ganglia, which could be mistaken for metastatic lymphadenopathy if the celiac ganglia have a nodular configuration and uptake higher than bone marrow. Uptake in celiac, cervical, and sacral ganglia has been reported previously as an important pitfall in Ga-PSMA-HBED-CC PET for prostate cancer. In our patients, only celiac ganglion uptake was visualized. Advances in PET scanner technology may cause physiologic uptake of F-fluciclovine in celiac ganglia to become more visually distinguishable from muscular uptake in adjacent diaphragmatic crura.
我们呈现了 4 例前列腺癌患者行 F-氟代脱氧胸苷 PET 的病例，这些患者的腹腔神经节有生理性摄取，若腹腔神经节呈结节状并有高于骨髓的摄取，则可能被误诊为转移性淋巴结病。此前，镓-PSMA-HBED-CC PET 用于前列腺癌时，已报道腹腔神经节、颈神经节和骶神经节的摄取是一个重要的陷阱。在我们的患者中，仅可见腹腔神经节摄取。PET 扫描仪技术的进步可能会使 F-氟代脱氧胸苷在腹腔神经节中的生理性摄取与相邻膈肌脚的肌肉摄取在视觉上更易区分。
