增强CT诊断腮腺多原发性肿瘤的价值研究

Diagnostic value of enhanced CT in multiple primary tumors in parotid gland

目的探讨腮腺多原发性肿瘤(multiple primary tumors,MPT)的临床特点、病理类型及影像学表现,分析增强CT诊断腮腺MPT的价值。方法对2013—2016年在首都医科大学附属北京友谊医院口腔科行腮腺肿瘤手术治疗的285例患者中的22例MPT患者的临床病历资料、影像学资料及病理报告进行回顾性分析。结果在22例腮腺MPT中,沃辛瘤17例,占77.3%(17/22)。腮腺MPT增强CT检查的检出率为83.3%,高于B超检查的检出率(52.6%)。单侧多发的腮腺肿物,增强CT检查的检出率为B超的2倍。结论沃辛瘤是最常见的腮腺MPT,完善增强CT检查有助于术前发现腮腺MPT,从而帮助确定手术方案。

Objective To evaluate clinical characteristics, pathology and imaging manifestation of multiple primary tumors （MPT） in parotid gland, and to analyze the value of enhanced CT in the deagnosis of parotid MPT. Methods Retrospectively analyze the medical histories of 22 patients with MPT among 285 patients with parotid gland tumors from 2013 to 2016. Results Seventeen cases were Warthin＇s tumor, accounting for 77.3% of MPT in parotid gland. The detection rate of CT was 83.3%, higher than B-uhrasonography. For unilateral MPT in parotid gland, the detection rate of CT was 2 times of B-ultrasonography. Conclusion Warthin＇s tumor is the most common type of MPT in parotid gland. Enhanced CT examination may help find MPT in parotid gland before the surgery, which helps to make surgery plan.
