Hepatic paragonimiasis revealed by FDG PET/CT.
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.
