Abstract:
Objective To evaluate CT imaging and pathological features of maxillofacial malignant myoepithelioma (MME). Methods A total of eight patients with pathologically confirmed MME of the maxillofacial region were underwent non-enhanced and contrast-enhanced CT scans.CT features of the lesions were assessed as follows:location,number,shape,size,enhancement pattern and CT number on non-enhanced and contrast-enhanced scan.CT features were compared with the pathological results.Results All the lesions were unilateral,in which mixed type with clear cells and spindle cells in 5 cases,mixed type with epithelioid cells and plas-ma cells in 2 cases,and clear cell type in one case.8 cases were manifested as lobulated mass.On non-enhanced scan,the density of all the lesions were hetergeneous with cystic area,1 case with calcification and 2 cases with bone destruction.On the contrast-en-hanced CT,all the lesions were showed hetergeneously moderate or obvious enhancement,and cystic,line and crack areas without the enhancement were observed.Minor vessel and spiculate protuberance of marginal zone on the arterial phase were observed in most le-sions.Conclusion MME has different pathological subtypes and characteristic CT features.CT is an effective method to diagnose MME.
