摘要目的 分析肺泡状棘球蚴病的CT表现特征,评价CT诊断该病的价值.方法 回顾性分析26例经病理确诊或临床综合诊断为肺泡状棘球蚴病的CT表现特征及各种表现的病理基础.结果 双肺多发病灶18例,一侧肺多发病灶6例,双肺单发病灶2例.其中病灶为肿块结节混合型17 例,结节型8例,1例为单发肿块.26例中24例病灶边缘可见分叶状或锯齿状突起,13例病灶内可见不规则空洞、空泡,18例病灶内可见钙化,14例病灶邻近的肺组织内见到少量斑片或条索影,20例邻近胸壁的病灶处胸膜增厚明显,病灶以宽基底与胸壁相贴.结论 肺泡状棘球蚴病有较明显的CT表现特征,CT检查能为该病的诊断提供重要价值.

abstractsObjective To analyze the CT features of lung alveolar echinococcosis and assess the value of CT scanning for the diagnosis of this disease. Methods The CT features of lung alveolar echinococcosis in 26 patients diagnosed pathologically or clinically were reviewed retrospectively and correlated with histopathology.Results Lung alveolar echinococcosis appeared as multiple lesions bilaterally in 18 patients, as multiple lesions unilaterally in 6 patients, and as single lesion bilaterally in 2 patients. Seventeen cases presented as masses and nodules,8 patients presented as nodules,1 patient presented as a mass. Lobulation and spiculation were showed in most lesions, irregular cavity or bubble-like opacity in 13 patients,calcification in 18 patients,a patchy area or fibrotic cord around lesion in 14 patients. Pleural thickening adjacent to the lesion in 20 patients. Conclusion Lung alveolar echinococcosis has characteristic features on CT, and CT can provide important information for the diagnosis of lung alveolar echinococcosis.
