Computed tomography and magnetic resonance imaging findings of lymphoepithelial carcinoma in parotid gland: a report of 6 cases / 中华全科医师杂志

ABSTRACT

To summarize the imaging characteristic of parotid lymphoepithelial carcinoma (LEC) by retrospective analyses of computed tomography (CT) and magnetic resonance imaging (MRI) findings for 6 cases of parotid LEC confirmed by operation and pathology and review the relevant literatures.All lesions were located in unilateral parotid.There were single (n =5) and multi-module fusion (n =1).All were located in superficial lobe of parotid gland.And deep lobe (3/6) was involved.An infiltration of casting shape was found along superficial parotid (4/6).There was an irregular margin with small spines,uniform density and signal and above moderate enhancement.An infiltration of casting shape along superficial lobe,uniform density and signal and rich blood supply suggest a diagnosis of LEC.
