肺黏液表皮样癌的CT表现

Mucoepidermoid Carcinoma of the Lung

目的探讨肺黏液表皮样癌的CT表现及其诊断价值。资料与方法搜集10例经手术及病理证实为肺黏液表皮样癌患者资料,分析其CT表现,并回顾近年国内外相关文献。结果肺黏液表皮样癌表现为气管、支气管内或肺内孤立性结节、肿块,呈卵圆形或分叶状,可伴有阻塞性肺炎或肺不张,部分可见点、片状钙化,注射对比剂后肿块呈中度强化。结论肺黏液表皮样癌的CT表现具有一定特征性,结合临床资料,能为该病诊断提供帮助。

Objective To determine the computed tomography （CT） findings of mucoepidermoid carcinoma of the lung and improve the diagnosis. Materials and Methods CT findings of ten cases confirmed by pathology were studied with review of the literatures. Results On CT images, the tumors were seen as endotracheal or endobronchial nodules which were either smoothly oval or lobulated and punctate calcification was seen in some lesions. Some were illustrated with obstructive pneumonia or atelectasis. Mild enhancement was shown after the administration of the contrast medium. Conclusion Mucoepidermoid carcinoma of the lung has special characteristics in CT images. Combined with clinical data, CT can be helpful to diagnose the disease.
