中文摘要 | 一位70歲無症狀男性,以氟-18-去氧葡萄糖(18F-FDG)進行全身正子斷層掃描,發現有高代謝性病變於乙狀結腸區。之後,進行大腸鏡檢查,顯示有一息肉距離肛門25公分,穿刺切片病理論斷為管絨毛狀腺瘤(villotubular ademona),然此息肉外科仍疑為惡性,經手術切除發發現有一3.5×2.4×1.5公分的蕈狀腫瘤位於乙狀結腸,病理診斷為腺癌併絨毛狀腺瘤。此一發現,顯示正子斷層描偵測到的腺瘤可能有惡性變化,由於腺瘤被認為是有可能轉變成惡性,因此正子斷層掃描極有價值用來偵測腺瘤轉變成腺癌。 |
英文摘要 | A 70-year-old asymoptomatic man, who underwent whole-body positron emission tomography (PET) with 18F-fluo-rodeoxyglucose, was found to have a lesion in the signmid colon reion. Furthermore, colonscopy examination revealed a polyp in a distance 25 cm to anus. Biopsy of the polyp was performed and histopathological study showed to be villotubular adenoma. However, the possibility of malignancy can't be ruled out. A low anterior resection for rectosigmoid colon was then performed and a 3.5×2.4×1.5 cm mass was found. Histopathological study showed an adenocarcinoma with malignant change. Colonic adenomas are considered to have potential for malignant transformation. Therefore, it is noteworthy that PET can be used in the detection of adenoma with malignant change. |
