摘要
目的：探讨腮腺良、恶性肿瘤的CT表现及鉴别诊断要点，以提高诊断准确率。方法：收集整理我院2011年6月1日—2014年7月31日的77例诊断腮腺肿瘤并经病理证实患者的CT影像资料，其中良性肿瘤45例，恶性肿瘤25例，非肿瘤7例，分析其CT影像表现特征，判定肿物的良恶性并与病理结果对照，比较其诊断符合率及鉴别要点。结果：CT诊断符合率83.1%（64/77），其中良性肿瘤诊断的符合率为84.4%（38/45），恶性肿瘤为88.0%（22/25）。良、恶性肿瘤在发生部位、形态、边界、侵袭及淋巴结转移方面上差异均有统计学意义（P<0.05）。结论：CT可较准确诊断腮腺良、恶性肿瘤，其影像学表现具有各自特点，如肿块发生于深部、形态不规则、边界不清晰，伴随淋巴结转移，常提示为腮腺恶性肿瘤可能性大。
Abstract
Objective: In order to improve the diagnostic accuracy, benign and malignant parotid gland were observed in CT images. Methods: The CT images of 77 patients with parotid gland tumors in our hospital from June 1st 2011 to July 31 2014 were collected. Forty-five cases were pathologically confirmed of parotid benign tumor. Twenty-five cases were malignant tumor, and seven cases were non-tumorous. The CT characteristics were analyzed and compared with pathologic findings. The CT diagnosis correspondence rate and differential diagnosis features were studied. Rseults: The rate of CT diagnosis correspondence was 83.1%(64/77), in which benign tumor diagnosis correspondence rate 84.4%(38/45) and malignant parotid gland diagnosis correspondence rate 88.0%(22/25). The location, shape, border area, invasiveness and lymph node metastasis images of parotid gland benign tumor were significantly different from those of malignant parotid gland(P<0.05). Conclusion: According to the image characteristics in CT, the benign or malignant parotid gland can be accurately diagnosed. Tumor located in deep lobe or cross depth-superficial two leaves and with irregular shape, unclear boundary and lymph node metastasis can be diagnosed as malignant tumor.
