目的：通过分析肺黏液表皮样癌的CT表现特点,提高该病的诊断正确率。方法回顾性分析经手术病理证实的15例肺黏液表皮样癌的CT表现,并结合文献探讨其CT表现特点。结果肿瘤位于右侧支气管8例,左侧支气管6例,左肺叶周边1例。7例肿块内见钙化灶。平扫肿块密度欠均匀,增强扫描强化程度不一,与肿瘤成分有关。10例伴有阻塞性肺炎、肺不张。3例伴有纵隔淋巴结转移。结论肺黏液表皮样癌多沿支气管长轴生长,其内多有钙化,增强扫描呈持续性强化,多伴有阻塞性改变,CT检查有一定的诊断及鉴别诊断价值。

Objective To improve the diagnostic accuracy by analyzing the computed tomography ( CT) characteristic performance of mucoepidermoid carcinoma of the lung. Methods CT findings 15 cases proved by pathology of mucoepidermoid carcinoma of the lung were retrospectively analyzed,and CT characteristic performance were studied by reviewing the literatures. Results The mucoepidermoid carcino-ma were located in right bronchial of 8 cases,left bronchial of 6 cases,peripheral part of the lung of 1 case. Calcification was seen in 7 mas-ses. Most masses density was not homogeneous at plain scanning. Venous phase have significantly enhanced compared with arterial phase. Ten cases showed obstructive pneumonia and atelectasis,3 cases with mediastinal lymph node metastases. Conclusion Multiple mucoepidermoid carcinoma of the lung grows extension of the long axis of bronchial,calcification be seen in most of patients. The enhanced mode of the lesions appeared as continuous progressive enhancement,some were illustrated with post obstructive pneumonia or atelectasis,CT have a certain value of diagnosis and diffenertial diagnosis.
