目的:探讨肺炎性假瘤的X线、CT表现及其特征。方法:对30例经手术病理证实肺的炎性假瘤病人进行胸部X线片、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,长毛刺等征像,对假瘤诊断具有重要意义。结论:全面分析假瘤的影像学特征,重视病人肺内感染病史,提高本病诊断的准确率是可能的。
Objective: To investigate the X-ray and CT findings of lung inflammatory pseudotumor and its characteristics. Methods: Thirty X-ray and CT scans of inflammatory pseudotumor confirmed by surgery and pathology were performed. The imaging features of the patients were analyzed. Results: During the stable stage of pseudotumor, most of the masses had complete capsule with smooth and spherical boundaries. Acute lesions, the foci of inflammatory infiltration, no capsule formation, the lesions were mostly clumps. Necrosis of the cavity mass, pleural adhesions, such as long burr signs, the diagnosis of pseudotumor is of great significance. Conclusion: It is possible to analyze the imaging features of pseudotumor comprehensively, attach importance to the history of pulmonary infection and improve the diagnostic accuracy of this disease.
