【摘要】：目的探讨大气道黏液表皮样癌的多层螺旋CT表现。方法搜集2005年至2012年间经手术或支纤镜病理证实的9例气管、大支气管黏液表皮样癌患者资料,对病灶的多层螺旋CT特征进行评价。结果位于气管、主支气管的瘤灶3例,最大径20 mm,表现为息肉样软组织密度影向管腔内突出,无阻塞性改变。位于中间段支气管、叶或段支气管的瘤灶6例,均表现为球形病灶,最大径20~68 mm;阻塞性肺不张1例,阻塞性肺炎6例。所有瘤灶均表现为表面光滑的均匀软组织密度影,CT值约(54±16)HU,增强后均明显均匀强化,强化前后差值为(64±14)HU。所有患者均未发现肺门、纵隔淋巴结增大,胸腔积液或胸膜增厚。结论大气道黏液表皮样癌好发于中青年,多位于主支气管以下的大气道,瘤灶强化明显,常伴有阻塞性肺炎或肺不张。
[Abstract]:Objective to investigate the multi-slice spiral CT findings of mucoepidermoid carcinoma of the atmospheric tract. Methods from 2005 to 2012, 9 patients with mucoepidermoid carcinoma of trachea and bronchi proved by surgery or bronchoscopy were collected and the features of multi-slice spiral CT were evaluated. Results 3 cases were located in the trachea and the main bronchus with the maximum diameter of 20 mm. The results showed that the density of polypoid soft tissue protruded into the lumen without obstructive changes. 6 cases were located in the middle bronchus, lobes or segmental bronchi, all showed spherical lesions with a maximum diameter of 2068 mm, obstructive atelectasis in 1 case, obstructive pneumonia in 6 cases. The CT value of all tumor foci was about 54 卤16 HUU, and the difference before and after enhancement was 64 卤14 Hu. No hilar, mediastinal lymph node enlargement, pleural effusion or pleural thickening were found in all patients. Conclusion the mucoepidermoid carcinoma of the atmospheric tract is more common in young and middle-aged people, most of them are located in the atmospheric tract below the main bronchus, and the tumor foci are obviously enhanced, often accompanied by obstructive pneumonia or atelectasis.
