A 72-year-old asymptomatic man with a hepatic lesion incidentally detected by ultrasonography in routine examination undertook fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography for further evaluation. The images revealed increased FDG activity in the lesion, which was suggestive of malignancy. However, the pathologic examination demonstrated that the lesion was a granuloma caused by Paragonimus westermani, a lung fluke. Although increased FDG activity in the lung due to P. westermani infection is expected and reported previously, such lesion identified in the liver by FDG positron emission tomography/computed tomography is unusual.
一位 72 岁无症状男性,在常规体检的超声检查中偶然发现肝脏病变,为进一步评估,行氟脱氧葡萄糖(FDG)-正电子发射断层扫描/计算机断层扫描。图像显示病变部位 FDG 活性增加,提示恶性肿瘤。然而,病理检查显示病变为卫氏并殖吸虫引起的肉芽肿。尽管先前已有报道并预期卫氏并殖吸虫感染可导致肺部 FDG 活性增加,但 FDG 正电子发射断层扫描/计算机断层扫描在肝脏中发现此类病变并不常见。
