肺炎性假瘤的影像学诊断(附33例分析)

The imaging diagnosis of the inflammatory pseudotumor of the lung (report of 33 Cases)

目的 :探讨肺炎性假瘤的X线、体层、CT表现及其特征。方法 :对 33例经手术病理证实肺的炎性假瘤病人进行胸部X线片、体层及CT扫描 ,对其影像学特征进行了分析研究。结果 :假瘤稳定阶段时 ,多数肿块包膜完整 ,边界光滑呈球形 ,病灶急性阶段时 ,灶周有炎性浸润 ,无包膜形成 ,病灶多呈团块状。肿块内空洞坏死 ,胸膜粘连 ,长毛刺等征象 ,对假瘤诊断具有重要意义。结论 :认为炎性假瘤术前诊断不能仅靠临床资料 ,应以X线及CT检查为主 。

Objective:To investigate the X ray and CT features of inflammatory pseudotumor.Methods:33 cases of pulmonary inflammatory psedotumor psedotumor confirmed by operation and pathology were examined by X ray and CT imaging features were analyzed.Results:When the pseudotumors of lung were in the stable stage,most masses were ball shaped with periphery smooth,and had intact capsules.When the disease was in the acute no capsule appeared.The CT finding including necrosis of cavity in the mass,local plural thickness and adhesion were of great significance in diagnosis of this disease.Conclusion:It is possible to increase the diagnostic rate by analysing the X ray and CT imaging features.
