60例肺炎性假瘤的影像学分析与研究

Imaging evaluation of 60 cases with pulmonary inflammatory pseudotumor

目的探讨和研究肺炎性假瘤的X线、CT表现及其特征,以提高正确诊断率。方法对60例经手术病理证实的肺炎性假瘤病人的胸X线片和CT影像表现进行分析研究。结果稳定阶段多数假瘤包膜完整,边界光滑呈球形或方形;急性阶段时,病灶周围有炎性浸润,无包膜形成,病灶多呈团块状;当肿块内出现空洞坏死、胸膜粘连及长毛刺等征像,对假瘤诊断具重要价值。结论全面分析假瘤的影像学特征,重视病人肺内感染病史,可提高本病诊断的准确率。

Objective To explore the imaging features of pulmonary inflammatory pseudotumor with X-ray and computed tomography（CT）.Methods Sixty cases of the inflammatory pseudotumor of lung proved by the operative pathology were retrospectively performed X-ray radiograph and the thoracic CT.Results In the stable or chronic stage,the pseudotumors were in a ball-like or square shape with the sharp borders.But in acute or inflammatory stage,the borders of the mass was indistinctive with inflammatory infilitration.With the signs performed as the cavities,pleural adhesion and spiculation,it might be helpful in diagnosis of the inflammatory pseudotumors.Conclusion To analyze the imaging signs and clinical features can improve the diagnostic accuracy.
