摘　　要：目的探讨CT对大气道富血供肿瘤的鉴别诊断价值,提高术前诊断的准确性.方法回顾性分析41例经病理确诊大气道富血供肿瘤患者的临床、CT资料,包括17例黏液表皮样癌(MEC),13例类癌(CAT),7例炎性肌纤维母细胞瘤(IMT),4例血管球瘤(GT).结果MEC和IMT发病年龄较CAT和GT年轻(P<0.05);MEC和IMT在病灶大小、生长方式、密度、CT强化值方面无明显差异(P≥0.05).MEC和CAT多发生在主支气管,分别占64.7%(11/17)和76.9%(10/13);4例GT均发生在气管.CAT病灶较大,11例表现为腔内外或腔外生长,5例可见钙化.GT增强呈进行性强化,平均CT强化值为(115.25±23.61)HU,与其他肿瘤相比差异无统计学意义(P≥0.05).结论MEC和IMT发病年青,MEC和CAT易发生在主支气管,CAT病灶较大且易向腔外生长、可发生钙化,GT渐进性明显强化,确诊仍需病理学检查.Objective To explore the value of CT in the differential diagnosis of hypervascular tumors in the large airway,and to improve the accuracy of preoperative diagnosis.Methods Clinical and CT data of 41 patients with pathologically confirmed hypervascular tumors in the large airway were analyzed retrospectively,including 17 mucoepidermoid carcinoma(MEC)cases,13 carcinoid tumors(CAT)cases,7 inflammatory myofibroblastic tumor(IMT)cases and 4 glomus tumor(GT)cases.Results The age of MEC and IMT patients were younger than those of CAT and GT patients(P<0.05).There were no significant differences in the lesion size,growth pattern。density and CT enhancement value between MEC and IMT(P≥0.05).MEC and CAT were mostly in the main bronchi,accounting for 64.7%(11/17)and 76.9%(10/13),respectively;4 GT occurred in the trachea.The lesions of CAT were large,11 of them grown both in and out of the cavity,5 of them showed calcification.GT showed progressive enhancement with an average CT enhancement value of(115.25±23.61)HU,which was no significant difference compared with the other tumors(P≥0.05).Conclusion The age of MEC and IMT patients are relatively young.MEC and CAT are mainly located in the main bronchus.CAT lesions are large and usually grow outside the lumen,and calcification may occur.GT enhanced gradully and obviously.The pathological examination is still required for diagnosis.
