摘要

Paragangliomas are rare tumors of neural crest origin that arise from the extra-adrenal autonomic paraganglia. A nonfunctioning paraganglioma could be discovered incidentally on imaging studies. Herein, we report the case of a 68-year-old man with early-stage lung cancer underwent a post-operation staging fluorine-18-fluorodeoxyglucose (F-18 FDG) positron emission tomography/computed tomography. A solitary well-defined nodule with extremely intense FDG was incidentally noted at the hepatogastric region. Finally, laparoscopic excision of the lesion was performed, and the diagnosis of malignant paraganglioma was confirmed by the pathological findings.

副神經節瘤是罕見的源自神經嵴的腫瘤，無功能性的副神經節瘤常在影像學研究中意外被發現。本篇病例報告一名68歲男性早期肺癌患者接受了術後F-18 fluorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography分期檢查，在肝胃區偶然發現一個邊界清楚且FDG訊號極強的孤立結節，經腹腔鏡切除病灶，病理結果證實診斷為惡性副神經節瘤。
