中文摘要

我們報告一位76歲之男性病患,臨床上僅表現出體重減輕的公斤,無明顯的血尿,卻在FDG正子電腦斷層攝影發現右腎腫瘤,接受腎臟切除手術,證實罹皂亮細胞腎痞。出院後在門診持續追蹤20個月,沒有發見類似轉移之病娃。就本例分析FDG正子掃描在腎細胞癌之攝取特點,病F土呈現代謝均等(isometabolic)及腫瘤中央壞死的模式,此腫瘤與腎臟組織沒有明確的分別界線。FDG正子掃描不能完全提供腫瘤異質性的生物學信息,因此對腎細胞為的診斷和為症分紋,似乎扮演不足勝任的角色。

英文摘要

This is a report of a 76-year-old man who had a body weight loss of 10 kg in two months. An isometabolic tumor arising from the right kidney was incidentally found on 18F-FDG PET/CT. Histopathological examination of the excised specimen revealed a clear cell renal carcinoma. FDG-PET has proved to be an effective modality in the diagnosis, staging, and monitoring of a variety of malignant conditions. The case reported here is of interest both for isometabolic manifestation, and for the morphologic features of the renal tumor on FDG PET. The role of PET in functional assessment of lesion is compromised in this case.
