摘　　要：目的探讨支气管黏液表皮样癌(BMEC)的CT表现及临床病理特点,提高临床诊断的准确性.方法回顾性收集经病理确诊的BMEC患者的临床及CT影像资料,共18例患者19个病灶纳入研究,观察并评估病灶的部位、数量、形态、直径、边缘、密度,分析病灶的强化方式、强化程度、局部外侵情况以及支气管管腔狭窄程度.结果18例患者中发热2例,咳嗽6例,咳嗽、咳痰5例,合并咯血1例,胸痛2例,胸闷1例,声音嘶哑2例.肿瘤位于左右肺的比例约为2︰1,位于主支气管内10例(52.6%),叶及段支气管9例(47.4%),其中管壁浸润型最多(57.9%),13例可见支气管局部外侵征象,6例可见支气管截断征;大多数病灶边界欠清晰(84.2%).管腔狭窄程度为1级1例,2级1例,3级7例,4级6例,5级3例.结论BMEC的CT表现具有一定的特征性,多表现为瘤体侵犯支气管壁,局部呈结节或肿块状.多平面重建(MPR)有助于病灶的检出,观察病灶与支气管壁的关系,避免不必要的漏诊和误诊.Objective To explore the CT features and clinicopathological features of brochial mucoepidermoid carcinoma(BMEC),to improve the accuracy of clinical diagnosis.Methods The clinical and CT data of patients with BMEC diagnosed by histopathology were collected retrospectively.A total of 18 patients with 19 lesions were included.The location,quantity,shape,diameter,edge and density of the lesions were observed and evaluated,and the enhancement degree,bronchial lumen stenosis degree and local invasion situation were analyzed.Results All of the 18 patients,including 2 cases of fever,6 cases of cough,5 cases of cough and sputum,1 case of hemoptysis,2 cases of chest pain,l case of chest tightness and 2 cases of hoarseness.The proportion of tumors located in the left and right lungs was 2 to 1.10 cases(52.6%)located in the main bronchus and 9 cases(47.4%)located in the lobar or segmental bronchi.Most of them were wall infiltrating type(57.9%).Signs of local extrabronchial invasion were observed in 13 cases and signs of bronchial truncation in 6 cases.The degrees of lumen stenosis were grade 1 in 1 case,grade 2 in 1 case,grade 3 in 7 cases,grade 4 in 6 cases and grade 5 in 3 cases.Conclusion The CT findings of BMEC have certain characteristics.Most of the tumors invaded the bronchial wall and showed nodules or masses locally.Multiplanar reconstruction(MPR)is helpful to detect the lesions,observe the relationship between the lesions and the bronchial wall,and avoid unnecessary missed diagnosis or misdiagnosis.
