目的分析大涎腺良性淋巴上皮病变的CT表现,以提高对该病的认识.方法回顾性分析11例经临床和病理证实的大涎腺良性淋巴上皮病变的CT表现并复习相关文献.所有患者均行CT平扫,其中5例行增强扫描.对病灶的部位、数目、形态、边缘、密度及强化特征等进行观察分析.结果 11例病变中发生于腮腺8例,颌下腺3例.7例双侧多发,4例单侧单发.根据CT表现可分为多发结节型、单发肿块型和弥漫浸润型.以多发结节型最多见,其典型表现为双侧腮腺和(或)颌下腺腺体弥漫性肿大,密度不均匀性增高,见多发结节样软组织密度影及多发囊状低密度影,增强后呈不均匀强化,结节实性部分为中等至明显强化,囊状低密度不强化.结论尽管大涎腺良性淋巴上皮病变的CT表现多样,但仍具有一定特点,能为临床诊断和选择治疗方式提供帮助.

Objective To analyze the CT findings of benign lymphoepithelial lesion (BLEL) of major salivary glands.Methods The CT findings of 11 cases with BLEL which were clinically and pathologically confirmed were analyzed.The relevant literatures were reviewed.All the patients received plain CT.Among them,5 patients had contrast CT as well.The location,number,shape,margin,density,and enhancement characteristics of the lesions were observed.Results Of 11 BLEL,8 lesions were located in the parotid gland,three in the submandibular gland.There were 7 cases with bilateral multiple lesions,and 4 cases with unilateral solitary lesion.BLEL of major salivary gland could be classified into three types according to the CT findings,including multinodular type,solitary mass type,and diffusely infiltrating type.Multinodular type was the most common type.The typical CT findings of the lesion included diffusely enlargement of bilateral parotids and (or) submandibular glands,heterogeneous increase of density of the parenchyma with multiple soft tissue density nodules,and multiple cystiform hypodense.On contrast-enhanced CT,the lesions mostly manifested as heterogeneous enhancement.The solid part of the nodules showed moderate or marked enhancement.However,the cystiform hypodense showed no enhancement.Conclusion Although the CT findings of BLEL of major salivary glands are variable,they still share some common characteristics,which are useful in the clinical diagnosis.
