隐源性机化性肺炎的影像学特点

目的回顾性分析5例隐源性机化性肺炎(COP)的影像学特点。方法收集经病理证实的COP患者5例,行胸部CT扫描。将COP的CT表现分为实变、磨玻璃样变、肺结节、线样或网格样改变等4型;病变的分布按单肺或双肺,上肺或下肺,胸膜下或沿支气管束走行等分类,对病变的类型及分布特点进行分析。结果5例患者中,4例可见肺实变,3例可见磨玻璃样变,2例可见肺结节改变,1例可见网格样改变,常多种表现混合存在。肺实变常在胸膜下或沿支气管血管束走行分布。磨玻璃样变和肺结节分布无特异性。结论COP最常见的是肺实变和磨玻璃样变。磨玻璃样变分布特征不具有特异性,而肺实变多表现为沿支气管血管束周围或胸膜下的分布特征。

Radiological features of cryptogenic organizing pneumonia

Objective To explore the radiological features of cryptogenic organizing pneumonia (COP). Methods Five patients with COP were pathologically identified. The chest CT scanning was performed in all patients. The radiological features of COP were classified into four types according to pulmonary consolidation,ground grass opacity (GGO),nodule,and liner or reticular lesion. The distribution of lesions were classified according to the single or double lung fields,upper or lower lung field,or the surrounding bronchovascular bundle or subpleural area. The radiological types and distributions of the lesions were analyzed. Results Among these 5 patients,pulmonary consolidation was found in 4 patients,ground grass opacity in 3 patients,nodules in 2 patients,and reticulation in one patient. Various radiological features were also observed at the same time. The pulmonary consolidation was distributed along the bronchovascular bundle or subpleural area. The distribution of GGO and pulmonary nodules were nonspecific. Conclusions The most common radiological features of COP were pulmonary consolidation and GGO. The distribution of pulmonary consolidation is specific. It extends along the bronchovascular bundle or located in the subpleural area.
