The CT findings of six patients (three symptomatic and three asymptomatic) with pulmonary paragonimiasis westermani were reviewed in correlation with the findings of radiography. Pleural changes were recognized in all cases on CT. In addition to pleural fluid collection and hydropneumothorax, which were demonstrated on plain radiograph, CT showed minimal pleural thickening and adhesion adjacent to the parenchymal lesions. CT showed round nodules of lower attenuation within a subpleural consolidation of triangular shape in two patients. Small air-filled cavities in a parenchymal lesion with central dense spots were demonstrated in two patients, and multiple cavities with irregular wall were seen in one patient. CT also demonstrated the parenchymal lesion with a tunnel-like cavity in one patient. These may represent the worm nodules, the worm within worm cysts, and the worm migration tract, respectively. These pulmonary lesions were located adjacent to the localized pleural thickening or adhesion in all six cases. CT was more useful than radiography in the diagnosis of pulmonary paragonimiasis westermani.
回顾了6例卫氏并殖吸虫病患者（3例有症状，3例无症状）的CT表现，并与X线检查结果进行对照。所有病例在CT上均可见胸膜改变。除了X线平片上显示的胸腔积液和气胸外，CT还显示在实质病变附近有轻微的胸膜增厚和粘连。2例患者在三角形的胸膜下实变区内可见低密度圆形结节。2例患者在实质病变内可见有中心致密点的小气囊腔，1例患者可见多个壁不规则的空洞。CT还显示1例患者的实质病变内有隧道样空洞。这些可能分别代表虫结节、虫囊内的虫体和虫体移行通道。所有6例患者的这些肺部病变均位于局限性胸膜增厚或粘连附近。在卫氏并殖吸虫病的诊断中，CT比X线检查更有用。
