【摘要】 目的 探讨肺炎性假瘤的CT表现及诊断价值。方法 分析8例经过手术或穿刺病理证实的肺炎性假瘤的CT表现进行回顾性分析。结果 肺炎性假瘤主要CT表现：(1)病变多位于胸膜下，可广基底，邻近胸膜可增厚；(2)6例呈球形，有完整假包膜者4例，边缘光整清晰。有部分假包膜者2例，部分边缘模糊。(3)2例呈不规则团块影，边缘有毛刺；1例肿块内可见小空洞形成。(4)病灶强化多较明显，其中5例CT值升高大于60HU，CT增强扫描有一定意义。(5)3例病灶周围有散在炎性浸润灶；(6)淋巴结肿大及胸腔积液少见。结论 肺癌、肺结核及肺炎性假瘤不易鉴别，要结合既往感染病史，重视CT增强扫描，注意动态随访，能够有助于肺炎性假瘤的诊断。穿刺活检是良好且有效的手段。【关键词】 肉芽肿，浆细胞，肺；体层摄影术，X线计算机；诊断

【Abstract】 Objective To investigate the CT features and value in diagnosing pulmonary inflammatory pseudotumor (PIPT).Methods The CT imaging features of 8 cases of PIPT confirmed by surgery or pathology were analysed retrospectively.Results The main CT findings were as follows:(1)The lesions were usually located peripherily.The bases were extensively adhesive to pleural with localized pleural thickening.(2)6 cases assumed the sphere,4 cases had completely false packages membrane,the edge was smooth.2 cases had partial false packages membrane,partial edge was blurry.(3)2 cases assumed the irregular briquetting shade,the edge have the burr;1 combined with small cavitation aroundly.(4)The focus of infection strengthens many is obvious,five is bigger than 60HU,The CT enhancement scanning has the certain significance.(5)3 cases focus of infection has the inflammation to infiltrate.(6)The lymph node tumescent and the chest water is rare.Conclusion The lung cancer,pulmonary tuberculosis and pneumonia vacation lump is not easy to distinguish,must unify infects the medical history formerly,takes the CT enhancement scanning dynamically,the attention makes a follow-up visit,can be helpful to pneumonia vacation lump diagnosis.The puncture biopsy is good also the effective method. ......
