A 70-year-old woman was admitted to our hospital for evaluation of a nodular shadow and an apparent cavity in the right middle lung field. Transbronchial biopsy and percutaneous needle biopsy had failed to result in a diagnosis. Serial chest X-ray films revealed slight regression of the nodule without therapy. Pulmonary dirofilariasis was diagnosed after open-lung biopsy and Ouchterlony's double diffusion test. Cavity formation and spontaneous regression are rare in pulmonary dirofilariasis.
一名70岁女性因右肺中叶结节状阴影及明显空洞入院评估。经支气管活检和经皮针吸活检均未能确诊。系列胸部X线片显示，未经治疗结节略有缩小。经开胸肺活检及奥克特洛尼双向扩散试验后诊断为肺丝虫病。肺丝虫病出现空洞形成和自然消退较为罕见。
