一位46歲男性食道癌患者進行氟-18-去氧葡萄糖正子-電腦斷層造影以做爲腫瘤監測。患者在臨床上並無症狀,同時正子造影亦無異常發現。然而仔細觀察電腦斷層影像及其前導影像,可以發現內植式中央靜脈導管斷裂並移動至遠端,這是可能致命的醫療併發症。在臨床工作中,核子醫學醫師應認知此種可能性,俾使及早對患者進行正確處置。
We present a case of esophageal cancer underwent 18F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) on purpose of tumor surveillance. The patient is clinically asymptomatic. The FDG PET is negative for tumor recurrence. However, careful inspection of the CT and scout image revealed rupture of Port-A catheter with remote migration-a potential lethal iatrogenic complication. Such probability must be kept in mind shall it be recognized and handled in time.
