Low Risk Gastrointestinal Stromal Tumor With High FDG Metabolism
具有高氟化去氧葡萄糖代謝的低風險胃腸道基質瘤
摘要
Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the alimentary canal. However, calcification and intense fluorine-18-fluorodeoxyglucose (FDG) uptake in low risk GIST of patient is rare. A 50-year-old woman received FDG positron emission tomography/computed tomography (PET/CT) for tumor survey. FDG PET/CT showed a nodule with heterogeneously increased FDG uptake in the small intestine with a focal hot spot within the nodule and a peripheral calcified spot on CT. Five years and 7 months later, the nodule and calcified spot enlarged with more intense FDG uptake. Hence, the patient received small intestine resection. Pathologic reports revealed small intestine stromal cell tumor (GIST) with low risk of malignancy.

腸胃道基質瘤是消化道中最常見的一種黏膜下間葉層腫瘤。通常，在低惡性風險型腸胃道基質瘤的案例中，臨床上很少會看到病灶組織鈣化與高氟化去氧葡萄糖吸收的影像。本案例為一名曾接受氟化去氧葡萄糖正子斷層攝影之50歲女性，其影像顯示在小腸中有一非均質性高氟化去氧葡萄糖吸收的結節，結節中並發現一周邊鈣化的強氟化去氧葡萄糖吸收點。個案於五年七個月後再次接受正子斷層攝影追蹤，發現該結節與鈣化點的體積明顯增加，且仍呈現非均質性高氟化去氧葡萄糖吸收，於是安排個案接受腫瘤切除手術。病理報告事後證實，該具有高氟化去氧葡萄糖代謝的小腸基質瘤為低惡性風險型胃腸道基質瘤。
