摘要

一60歲男性病患因胸部電腦斷層檢查發現肺部有一逐漸變大的單一結節而被轉診實施氟－18-去氧葡萄糖正子射出斷層造影來評估此結節的特性。檢查結果顯現兩肺沒有確定病灶，但其兩側橫膈下壓、胸腔上、下徑增長、左、右心室肥大，尤其心室中膈特別明顯，經胸部X光及電腦斷層檢查證實這是因病患有嚴重肺氣腫所致。簡而言之，作者於此將報告一位肺氣腫病患肺部有單一結節，其正子射出斷層造影意外發現兩側心室異常之葡萄糖攝取。

A 60-year-old male presented with a solitary pulmonary nodule (SPN) in the right upper lobe by computed tomography (CT) of the chest. He was referred for 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) to evaluate the nature of the nodule. FDG-PET images showed downward displacement of both diaphragms with flattened upper boarder of the liver, elongated vertical dimension of the thoracic cavity, and increased radioactivity in the region of the stomach, while there was no definite lesion with increased FDG metabolism in the lungs. In addition, the following cardiac chamber abnormalities were found: thickened inter-ventricular septum, well visualization of the right and left ventricles-thicken free walls of the left and right ventricles. Follow-up chest radiography showed downward displacement of both diaphragms with elongation of vertical dimension of both lungs, consistent with emphysematous changes. CT of the chest with lung window demonstrated emphysematous changes of both lungs, consistent with pulmonary emphysema and enlargement of both ventricles, corresponding to secondary pulmonary hypertension with ventricular abnormalities. In summary, we discovered that incidental detection of unexpected cardiac abnormalities by FDG-PET in patient evaluated for SPN.
