摘　　要：目的:探讨腮腺少见病变的影像学表现,提高对其认识水平。方法:回顾性分析经临床及病理证实的38例腮腺少见病变的CT或MRI资料。结果:嗜酸细胞腺瘤向咽旁间隙生长是其特征性表现;基底细胞腺瘤有双期持续强化特点;肌上皮瘤和肌上皮癌影像表现无特异性;脂肪瘤可见脂肪成分;婴儿毛细血管瘤有血管流空信号;木村病表现为腮腺弥漫性肿大,累及皮肤及皮下组织;表皮样囊肿、皮样囊肿、潴留囊肿病灶内均无强化;钙化性上皮瘤常位于腮腺区外侧皮下,发生部位有一定特点;良性淋巴上皮病变表现为双侧腮腺弥漫性肿大伴多发囊性肿块或小结节;淋巴上皮癌表现为多发囊性肿块时与良性淋巴结上皮病变及转移性鳞癌鉴别困难;腮腺癌2例均为腺泡细胞癌;淋巴瘤常有原发淋巴瘤病史,伴全身多发淋巴结肿大;转移瘤有原发恶性肿瘤病史,影像学表现与原发肿瘤密切相关。结论:部分腮腺少见病变具有一定的影像学特点,有助于鉴别诊断,确诊仍依靠组织病理学和免疫组化。Objective:To explore the imaging appearances of uncommon parotid diseases so as to improve the recognition.Methods:CT and MRI imaging of 38 cases with rare parotid diseases were retrospectively analyzed.Results:Oncocytoma growing into the parapharyngeal space was more characteristic.Basal cell adenoma had dual-phase continuous enhancement features.Myoepithelioma and myoepithelial carcinoma had no specific imaging performance.Lipoma had fatty density.Infantile capillary hemangioma had vascular washout effect.Retention cysts,epidermoid cysts,dermoid cyst lesions all had no enhancement.Calcifying epithelioma was usually located in parotid region subcutaneous,the site had some characteristics.Benign lymphoepithelial lesions showed bilateral diffuse parotid enlargement with multiple cystic mass,or multiple nodules.Lymphoepithelial carcinoma was difficult to distinguish with benign lymphoepithelial lesions or metastases of squamous cell carcinoma when showed multiple cystic masses.Kimura disease revealed diffuse parotid swelling and mass,involving the skin and subcutaneous fat layer.2 cases of parotid carcinoma were acinic cell carcinoma.Lymphoma often had a history of primary lymphoma,metastatic tumors had a history of primary malignancy,and the imaging appearance was closely related to the primary tumor.Conclusions:Some rare lesions of the parotid gland have certain imaging features,which is helpful to the diagnosis and differential diagnosis.But the final diagnosis still relies on histopathology and immunohistochemistry.
