摘　　要：目的:认识肺炎性结节的CT影像表现并评价CT对该病的诊断价值。方法:回顾性分析21例经临床或病理证实的肺炎性结节,观察病变的各种CT征象。结果:病变多位于两肺下叶,CT表现因病理过程不同可表现为局灶性渗出性改变或实质性结节。结节性病变的典型征象为密度均匀,病变-肺交界面规则清楚,或伴有“晕征”、长短不一的毛刺以及相邻胸膜广泛增厚、粘连。结论:病变区薄层扫描是提高对肺炎性结节CT变化特征认识的重要检查技术,进一步结合临床,必要时动态随访观察能大大提高对该病诊断的准确性。Objective: To identify the CT features of pulmonary inflammatory nodule (PIN)and to assess the value of CT in diagnosis of this disorder. Methods: Twenty - one PINs confirmed by clinic and pathology were analyzed retrospectively by CT imaging. The thin -slice scans were performed in interesting areas. Results: The most common locations of PIN were in both lower lungs. The CT findings were varied with pathological changes including local exudation and solid nodule. The main distinctive features of nodule were homogeneous density (n = 14), regular and well circumscribed margin (n = 11), periphery complained with 'halo sign' or spicules of various length(n = 16), and regional pleura! thicken and adherence (n = 7). Conclusion :The thin slice CT scan is the fundamental of observation and identifying PIN. Combining with the enhancement scan and dynamical follow- up, it will facilitate the diagnosis of the disease.
