摘要

Adenocarcinoma of ampulla of Vater is an uncommon malignancy with incidence of 0.5% of all gastrointestinal malignancy. Liver is the most common metastatic site, but it is unusual to occur in early stage with complete resection. Due to relative rare, detecting hepatic metastases from early stage adenocarcinoma of ampulla of Vater by F-18 FDG PET/CT is still under investigation. We present a case of early stage (T2N0M0) adenocarcinoma of ampulla of Vater, with hepatic metastases 1 year after complete resection of primary tumor. F-18 FDG PET/CT helps to confirm hepatic metastases which were equivocal on CT and MRI. Moreover, F-18 FDG PET/CT also detected an incidental rectal intramucosal adenocarinoma. The usefulness of F-18 FDG PET/CT to detect hepatic metastases from adenocarcinoma of ampulla of Vater and incidental colorectal malignancy is also evaluated.

華特氏壺腹癌是少見的腸胃道惡性腫瘤，僅占所有腸胃道惡性腫瘤的0.2～0.5％。肝臟是最常發生轉移的器官，但在早期完全切除的華特氏壺腹癌是不尋常的。因為病例數少，氟-18去氧葡萄糖正子電腦斷層造影（F-18 FDG PET/CT）在其原發及轉移腫瘤的偵測能力需進一步研究。我們報告一個早期壺腹癌經過完全切除，術後一年追蹤發現肝轉移的案例。氟-18去氧葡萄糖正子電腦斷層造影可以確認肝轉移病灶，比斷層掃描發現更多肝轉移病灶，而且意外發現早期直腸惡性腫瘤。這篇文章將討論氟-18去氧葡萄糖正子斷層造影在偵測華特氏壺腹癌肝轉移及早期大腸直腸癌的應用。
