Abstract

The case of a 48-year-old man with pulmonary paragonimiasis mimicking lung cancer on positron emission tomography with fluorodeoxyglucose (FDG-PET) imaging is reported herein. Plain radiography and computed tomography (CT) of the chest showed a nodular lesion at the left pulmonary hilum. Lung cancer was strongly suggested from standardized uptake values determined on FDG-PET imaging; however, repeat chest CT revealed the lesion to have decreased in size. Pulmonary paragonimiasis was subsequently diagnosed after sputum microscopy demonstrated operculated parasitic eggs. To the best of our knowledge, this is the first reported case of pulmonary paragonimiasis mimicking lung cancer on FDG-PET imaging.

摘要

本文报道了一例48岁男性，其肺吸虫病在氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）成像上表现为酷似肺癌。胸部X线平片和计算机断层扫描（CT）显示左肺门有一个结节性病变。根据FDG-PET成像测定的标准化摄取值强烈提示为肺癌；然而，重复胸部CT显示病变大小减小。痰显微镜检查发现有带盖的寄生虫卵后，随后诊断为肺吸虫病。据我们所知，这是首例在FDG-PET成像上表现为酷似肺癌的肺吸虫病病例。
