摘　　要：目的　探寻肺炎性假瘤的CT征象特点 ,以便与肺癌、肺结核瘤以及球形肺炎等球形病灶相鉴别。方法　搜集 31例经手术病理证实的肺炎性假瘤的CT资料进行回顾性分析。结果　肺炎性假瘤的主要CT表现 :(1 )类圆形 ,大都边缘光整的肿块 ,多为单发 ,直径在 3 .0cm左右 ,密度均匀。 (2 )局限性胸膜肥厚粘连 ,无胸水及钙化征象 ,肿块与增厚的胸壁之间有条状低密度影。 (3)病变中间层面一侧边缘垂直于胸膜呈刀切样改变。 (4)病灶边缘粗短毛刺。结论　CT检查对肺炎性假瘤的正确诊断与鉴别诊断是很有帮助的。Objective To study the CT features of pulmonary inflammatory pseudotumor so as to distinguish from spherical lesion of lung cancer,tuberculoma and sperical pneumonia.Methods We investigated retrospectively the data of the 31 cases with pulmonary imflammatory pseudotumor which were proved pathologically after surgery.Results The main CT findings were as follows:(1)circle-like mass,most of them were single,margin was smoothy,density was even,diameter was about 32.0 cm.(2)There were localized pleural thickening adhesion and strip-like low density lesion between mass and thickened chest wall.(3)The middle sections showed:lateral margins of the lesions perpendicular to pleura with a straight cut edge.(4)The edge of the lesion presented short and thick spiculation.Conclusion CT examination is very helpful to the correct diagnosis of pulmonary inflammatory pseudotumor.
