摘要
目的分析腮腺少见肿瘤的增强CT表现特征,为临床诊疗提供参考。方法采取回顾性研究方法 ,选取我院收治的70例腮腺少见肿瘤患者作为研究对象,分析不同病理学类型肿瘤在增强CT图上的病变位置、大小、形态、密度以及与周围结构之间的关系。结果本组70例中,确诊有3例软骨肉瘤(以囊性为主且含边缘钙化成分的肿块),12例肌细胞上皮瘤(多发于腮腺浅叶,少数病变可见钙化),15例脉管瘤(密度均匀或者不均匀、突出于腮腺表面),25例基底细胞瘤(多发于腮腺浅叶、病变内易见囊变,增强CT扫描可伴有增大的淋巴结),8例淋巴上皮囊肿(CT值密度比较高、囊液较为黏稠),7例腮腺脂肪瘤(脂肪密度肿块清晰、病变内可见纤维分隔)。基底细胞瘤在术前有1例被误诊为血管瘤,与病理不符;肌细胞上皮瘤术前被误诊为多行性腺瘤,与病理不符;软骨肉瘤在术前被误诊为神经源性肿瘤,与病理不符。结论腮腺少见肿瘤的增强CT影像表现各有不同,需要加强专业技术学习,以提高对其的认识。
Objective To analyze the enhanced CT features of uncommon parotid tumors to provide reference for clinical diagnosis and treatment. Methods A total of 70 patients with uncommon parotid tumors admitted to our hospital were review to analyze the location, size, shape and density of lesions of different pathological types of tumors on enhanced CT image and the their relation with surrounding structures. Results Among the 70 cases, there were three cases of confirmed hondrosareoma （mainly cystic lumps with components with peripheral calcification）, 12 cases of myocyte epithelioma （mostly on superficial parotid lobe, with calcification visible on a few lesions）, 15 cases of vascular tumor （with uniform or non-uniform density and protruding from the protid surface）, 25 cases of basal cell tumor （mostly on superficial parotid lobe, obvious cystic change within lesions, and enlarged lymph nodes in the enhance CT image）, 8 cases of lymphatic epithelial cyst （high density in CT image and sticky cyst fluid） and 7 cases of protid lipomyoma （clear fat density and lumps, and visible hyperdensity in lesions）. Before the operation, one case of basal cell tumor was misdiagnosed as hemangioma, which was not in conformity with pathological findings; myocyte epithelioma as superficial multiform adenoma, which was not in conformity with pathological findings; and hondrosarcoma as neurogenic tumor, which was not in conformity with pathological findings. Conclusion The manifestations of uncommon protid tumors in enhanced CT image are different. Therefore, professional technological learning shall be enhanced to improve the understanding of such manifestations.
