Objective:

To investigate and summarize the CT features of bronchial mucoepidermoid carcinoma (MEC) to improve the diagnostic accuracy of imaging.

Methods:

The CT data of twelve MEC patients confirmed by pathology from Aug. 2015 to Oct. 2017 in The Second Affiliated Hospital of Luohe Medical College were retrospectively analyzed and compared with pathological results.

Results:

Twelve patients presented with cough

expectoration

hemoptysis and chest tightness. Among them

two lesions were located in the trachea

three in the main bronchus

six in the segmental bronchus

and one in the right middle bronchus. Plain scan showed isodensity or slightly low densit

y. Calcifications were seen in four cases. Enhanced scan showed medium to obvious enhancement

and three cases had inhomogeneous enhancement.

Conclusion:

CT findings of bronchial mucoepidermoid carcinoma have certain characteristics. Multi-slice spiral CT (MSCT) scan plus enhanced scan and multi-planar reconstruction (MPR) can significantly improve the diagnostic accuracy.
