摘　　要：目的探讨炎性假瘤和周围型肺癌的不同CT表现和病理。方法回顾性分析经手术病理、穿刺活检和临床证实的63例长轴与支气管血管束平行的肺内孤立性肿块(SMPB),全部病例经CT扫描检查,根据影像学特征将SMPB分为梭形和楔形两大类,结合肿块的边缘、内部结构及胸膜的改变,分析其影像学特征,以鉴别炎性假瘤与周围型肺癌。结果梭形肿块29例,其中周围型肺癌18例(分别占全部病例的29%,梭形肿块的62%);炎性假瘤6例,肺结核2例,肺脓肿、类癌及转移癌各1例。楔形肿块34例,其中炎性假瘤25例(分别占全部病例的40%,楔形肿块的74%),周围型肺癌5例,肺结核3例,肺脓肿1例。结论综合分析肿块的形态学改变,结合SMPB的梭形和楔形征象,有助于周围型肺癌和肺内炎性假瘤的鉴别诊断,但需密切结合临床和病理。Objective To evaluate CT findings and pathology of inflammatory pseudotumor and peripheral cancer of lung. Methods The CT scannings of 63 patients with solitary mass paralld to bronchi-vessel （SMPB） were restrospectively reviewed. All were confirmed through surgery, pathology or clinical feature. These SMPB were classified into two groups： fusiforrn and wedgiform. Also the margin, air bronchogram, adjacent pleural thickness,and the other signs of SMPB were analyzed. Results There were 29 eases of fusiform lesion and 34 wedgeform respectively. Among the fusiform, 18 were peripheral cancer, 6 were inflammatory pseudotumor, and others were 3 eases of tuberculosis, 1 abscess, 1 metastatic tumor, and 1 carcidoid. Whereas among the 34 lesions of wedgeform, there were 25 eases of inflammatory pseudotumor and only 5 peripheral cancer as wedgelike, 3 tuberculosis and i abscess. Conclusion Summary analysis of morphology of SMPB （fusiform or wedgiform） will help the differential diagnosis of pseudotumor and peripheral cancer of lung, but association with clinical manifestation and pathology is needed.
