目的 :探讨肺炎性假瘤的临床特点 ,以期提高对本病的认识。方法 :回顾分析 12例肺炎性假瘤的临床症状、影像学表现、纤支镜检查及手术所见。结果 :本病发病率男性高于女性 ,主要症状有咳嗽、痰血、低热、胸痛。影像学表现为肺外周结节、球形、团块状影 ,典型者边缘清楚、密度均匀 ,也可边缘毛糙、分叶、毛刺 ,密度不均匀 ,伴空洞、钙化。纤支镜检查见支气管粘膜充血、有炎性分泌物或管腔呈外压性狭窄 ,支气管部位的炎性假瘤可呈息肉状新生物。结论 :肺炎性假瘤临床表现无特征性 ,误诊率高。影像学检查对鉴别诊断有一定帮助。当鉴别诊断有困难时 ,宜及时开胸探查 ,术中冰冻病理切片检查以决定术式 Objective: To investigate the clinical features of pulmonary inflammatory pseudotumor, with a view to raising awareness of the disease. Methods: Retrospective analysis of 12 cases of inflammatory pseudotumor clinical symptoms, imaging findings, bronchoscopy and surgical findings. Results: The incidence of the disease in men than women, the main symptoms are cough, sputum blood, fever, chest pain. Imaging findings of pulmonary nodules, spherical, mass shadow, typical edge clear, uniform density, but also rough edges, leaves, burrs, uneven density, with empty holes, calcification. Bronchoscopy bronchial mucosal examination see hyperemia, inflammatory discharge or lumen was external pressure stenosis, bronchial inflammatory pseudotumor can be polyps like new organisms. Conclusion: The clinical manifestations of pneumoconiosis are characteristic and the rate of misdiagnosis is high. Imaging examination of differential diagnosis have some help. When the differential diagnosis is difficult, timely exploration of thoracotomy, intraoperative frozen pathological examination to determine the surgical
