目的探讨多层螺旋CT(MSCT)对腮腺肿瘤的诊断价值。方法回顾性研究62例腮腺肿瘤的MSCT表现,所有病变均经手术病理证实。结果良性肿瘤包括多形性腺瘤17例、腺淋巴瘤13例、淋巴管瘤9例、脂肪瘤4例,恶性肿瘤包括黏液表皮样癌15例、腺泡细胞癌2例、囊腺癌1例、淋巴瘤1例。MSCT平扫可清楚显示病灶及其大小、形态和范围,增强扫描能显示肿物与周围大血管的关系,以及对周围组织的推移及侵犯。结论 MSCT在腮腺良恶性肿瘤鉴别诊断中具有重要作用,结合增强扫描可提高诊断准确率。
Objective To investigate the diagnostic value of multi-slice spiral CT (MSCT) for parotid gland tumor. Methods A retrospective study of 62 cases of parotid tumors MSCT performance, all lesions were confirmed by surgical pathology. Results There were 17 pleomorphic adenoma, 13 adenoma, 9 lymphangioma, 4 lipoma, malignant tumor including 15 cases of mucoepidermoid carcinoma, 2 cases of acinar cell carcinoma and 1 case of cystadenocarcinoma 1 case of lymphoma. MSCT scan can clearly show the lesion and its size, shape and scope, enhanced scan can show the relationship between the tumor and the surrounding large blood vessels, as well as the surrounding tissue and violations. Conclusion MSCT plays an important role in the differential diagnosis of benign and malignant parotid tumors. Combined with enhanced scanning, MSCT can improve the diagnostic accuracy.
