Pulmonary paragonimiasis is a relatively rare cause of lung disease revealing a wide variety of radiologic findings, such as air-space consolidation, nodules, and cysts. We describe here a case of pulmonary paragonimiasis in a 27-year-old woman who presented with a 2-month history of cough and sputum. Based on chest computed tomography (CT) scans and fluorodeoxyglucose positron emission tomography (FDG-PET) findings, the patient was suspected to have a metastatic lung tumor. However, she was diagnosed as having Paragonimus westermani infection by an immunoserological examination using ELISA. Follow-up chest X-ray and CT scans after chemotherapy with praziquantel showed an obvious improvement. There have been several reported cases of pulmonary paragonimiasis mimicking lung tumors on FDG-PET. However, all of them were suspected as primary lung tumors. To our knowledge, this patient represents the first case of paragonimiasis mimicking metastatic lung disease on FDG-PET CT imaging.
肺吸虫病是一种相对罕见的肺部疾病病因，可呈现多种放射学表现，如肺实变、结节和囊肿。我们在此描述一例27岁女性肺吸虫病病例，该患者有2个月的咳嗽和咳痰病史。根据胸部计算机断层扫描（CT）和氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）结果，怀疑该患者患有肺转移瘤。然而，通过酶联免疫吸附测定（ELISA）进行的免疫血清学检查诊断她感染了卫氏并殖吸虫。吡喹酮化疗后的胸部X线和CT随访扫描显示明显改善。已有几例肺吸虫病在FDG-PET上表现类似肺肿瘤的报道病例。然而，所有这些病例都被怀疑为原发性肺肿瘤。据我们所知，该患者是首例在FDG-PET CT成像上表现类似肺转移瘤的肺吸虫病病例。
