肺吸虫病是一种慢性人畜共患性寄生虫病, 近年来发病有增多趋势。由于其主要病变器官为胸肺,当该病出现在肺外时,极易造成误诊。肺吸虫病首次确诊率仅为11.40%,误诊率高达68.73%~88.60%,误诊最长病例达3年之久[1]。肺吸虫病的诊断要综合流行病学资料、临床表现、实验室检验、影像学检查和组织病理学结果。笔者报道了1例肝肺吸虫病,查阅文献并分析其18F-FDG PET/CT显像特点,旨在为临床鉴别诊断提供参考。

摘要: 笔者报道了1例肝肺吸虫病18F-氟脱氧葡萄糖 PET/CT显像的病例,该病临床较为少见,易误诊为肝细胞癌、胆管细胞癌或肝脓肿等。肺吸虫进入人体后可以导致多系统、多器官的病变,PET/CT作为全身检查可以发现更多器官的受累情况。笔者通过对该病例进行分析并对相关文献进行复习,加深了对肝肺吸虫病分子影像学特征的认识,以期对肝肺吸虫病作出更准确的诊断,加强认识,减少误诊。Abstract: The authors report a case of hepatic paragonimiasis with 18F-fluorodeoxyglucose PET/CT imaging, which is rare in clinic and easily misdiagnosed as hepatocellular carcinoma, cholangiocarcinoma or liver abscess. After entering the human body, paragonimiasis can lead to multi-system and multi-organ lesions. PET/CT as a systemic examination can find more organs involved, so as to make a more accurate diagnosis of liver paragonimiasis, strengthen understanding and reduce misdiagnosis.
