摘　　要：目的:分析37例肺炎性假瘤患者的HRCT征象,探讨其影像学特征及鉴别诊断意义。材料和方法:对37例经病理证实的肺炎性假瘤行常规和对病灶局部薄层扫描,分析总结病变的形态学特征,并与病理学改变进行对照研究,另随机选择同时期的周围型肺癌进行对照分析。结果:肺炎性假瘤多位于两肺下叶,邻近胸膜增厚、粘连,病灶密度偏低(平扫CT值15～60HU,平均26.9±13.5HU),与周围型肺癌比较有统计学差异,其形态以圆形/类圆形和不规则形多见,病灶内密度多不均匀,可见钙化及多发空洞,边缘呈平直状、周围见毛玻璃样改变及肺门纵隔无淋巴结肿大等征象对本病的CT诊断有意义。结论:肺炎性假瘤的部分HRCT征象能反映其病理特征,全面综合分析CT表现并结合临床病史有助于正确诊断。Objective： To study HRCT features of 37 cases of pulmonary inflammatory pseudotumor and assess their value in differential diagnosis. Materials and Methods： Thirty-seven cases pulmonary inflammatory pseudotumors （PIP） confirmed at resection and pathology with diameter≤3cm were performed HRCT scan after common CT scan. The morpbologic features of PIP with HRCT were analyzed and compared with pathological findings. 104 cases of peripheral lung carcinoma（PLC） were selected at the same time in random sampling as control. Results： The most common locations of PIP were at the margin of both lower lobes and associated with local pleural thickening and adhesion. The density of nodule in which CT attenuation value was 15-60HU （26.9±13.5HU） was lower than that of PLC. Most of them were round/round-like and irregular in shape. The interior density of lesion was inhomogeneous. The presence of calcification or multiple cavitations, straight margin sign, hole sign and without hilar and mediastinal adenopathy were of great significance in the diagnosis of such kind of disease. Conclusion： Some HRCT features of PIP could reflect their pathological findings. It is necessary to increase the diagnostic rate by comprehensive analyzing the HRCT features of PIP with the history of infection.
