摘要
目的探讨腮腺肌上皮癌(MC)的临床与CT表现,以提高对该病的认识及诊断准确率。方法搜集3例经手术病理证实的腮腺MC的临床及CT影像资料,复习相关文献,分析其CT特点。结果3例患者均为左侧腮腺单发的肿块,呈浅分叶状,密度不均匀,可合并钙化、囊变或坏死,增强扫描呈周边结节样明显不均匀渐进性强化,肿瘤周边及内部可见穿行的供血动脉,部分患者肿块同侧颈外动脉增粗、迂曲。结论MC的CT表现具有一定特征性,结合临床及实验室检查,有助于对该病的诊断。
Objective To investigate the clinical and CT imaging features of parotid myoepithelial carcinoma(MC)and improve the diagnostic accuracy of the disease.Methods Analyzing clinical and CT findings of three parotid MC cases confirmed by surgery and pathology and reviewing the literatures.Results All of the three patients presented with solitary masses of the left parotid gland with lobulated appearance and heterogenous density.Calcification,cystic degeneration and necrosis could be seen within the mass.On contrast-enhanced image,the masses showed an obvious,centripetal,and in-homogeneous enhancement pattern,with feeding artery around or across the tumor.The ipsilateral external carotid artery of the mass was dilated and tortuous in some cases.Conclusion The characteristic CT findings of MC combined with the clinical and laboratory examination could contribute to the diagnosis.
