目的提高对细支气管肺泡癌的认识及诊断水平。方法回顾分析经肺穿刺及手术后病理证实的6例细支气管肺泡癌的临床及CT表现。结果 6例炎症型细支气管肺泡癌3例初次诊断为炎症,经短期抗炎治疗后复查无吸收,CT引导下肺穿刺活检诊断为本病,3例拟诊为占位直接肺穿刺活检诊断为本病。结论炎症型细支气管肺泡癌表现特殊,影像学检查易误诊,短期抗炎治疗后随访可提高影像诊断的正确率,CT引导下穿刺活检是诊断此病的有效方法。 Objective To improve the awareness and diagnosis of bronchioloalveolar carcinoma. Methods The clinical and CT findings of 6 cases of bronchioloalveolar carcinoma confirmed by pathological examination after lung paracentesis and surgery were retrospectively analyzed. Results Three cases of inflammatory bronchioalveolar carcinoma were initially diagnosed as inflammatory and were non-absorbed after short-term anti-inflammatory treatment. CT-guided pulmonary biopsy was diagnosed as this disease. Three cases were diagnosed as direct lung biopsy The disease. Conclusions Inflammatory bronchioloalveolar carcinoma has a special manifestation. Misdiagnosis of imaging examination is easy. The follow-up after short-term anti-inflammatory treatment can improve the accuracy of imaging diagnosis. CT-guided biopsy is an effective method to diagnose this disease.
