Positron emission tomography (PET) using 18F-fluorodeoxyglucose (FDG) is useful in cancer diagnosis owing to its sensitivity to the differences in glucose metabolic rate between benign and malignant diseases, especially in the lung. One pitfall in PET imaging of lung disease, however, is the overlap in metabolic rate of inflammatory and neoplastic entities. Paragonimiasis is a food-borne parasitic disease that causes the pulmonary and pleural inflammation. We present two cases of pulmonary paragonimiasis that showed high uptake suggestive of tumor on FDG-PET CT images, both confirmed on histopathology by visualization of Paragonimus westermani eggs in the involved tissues.
使用18F-氟脱氧葡萄糖（FDG）的正电子发射断层扫描（PET）因其对良性和恶性疾病之间葡萄糖代谢率差异的敏感性，在癌症诊断中很有用，尤其是在肺部。然而，肺部疾病PET成像的一个陷阱是炎症和肿瘤实体的代谢率重叠。肺吸虫病是一种食源性寄生虫病，可引起肺部和胸膜炎症。我们报告两例肺吸虫病病例，其在FDG-PET CT图像上显示高摄取，提示肿瘤，两者均经组织病理学证实，在受累组织中可见卫氏并殖吸虫卵。
