INTRODUCTION
Pulmonary dirofilariasis is a rare pulmonary parasitic infection by the nematode Dirofilaria immitis. It is characterized by an asymptomatic pulmonary nodule usually seen on chest X-ray. The differential diagnosis of pulmonary dirofilariasis includes other pulmonary diseases, primary lung carcinoma and metastatic lung tumor.
CASE PRESENTATION
Pulmonary dirofilariasis was diagnosed in a woman who presented with interstitial pneumonia. Growth of the pulmonary nodule was detected subsequent to hemoptysis. The histological diagnosis was made based on a wedge resection performed under video-associated thoracic surgery (VATS).
CONCLUSION
Pulmonary dirofilariasis often varies in its clinical course. The diagnosis is best made using wedge resection under VATS.
引言
肺丝虫病是由犬恶丝虫引起的一种罕见的肺部寄生虫感染。其特征是在胸部X线检查中通常可见无症状的肺结节。肺丝虫病的鉴别诊断包括其他肺部疾病、原发性肺癌和转移性肺肿瘤。
病例报告
一名患有间质性肺炎的女性被诊断为肺丝虫病。咯血后发现肺结节增大。组织学诊断是基于在电视辅助胸外科手术（VATS）下进行的楔形切除术。
结论
肺丝虫病的临床病程通常多变。最好通过VATS下的楔形切除术进行诊断。
