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 investigate the clinical features, pathological types and imaging features of multiple primary tumors (MPT) in parotid gland, and to analyze the value of enhanced CT in the diagnosis of parotid MPT. Methods The clinical records, imaging data and pathological reports of 22 MPT patients from 285 patients undergoing parotid tumor surgery at Beijing Friendship Hospital Affiliated to Capital Medical University from 2013 to 2016 were analyzed retrospectively. Results In 22 parotid MPTs, 17 Wartsin tumors were found (77.3%, 17/22). Parotid MPT enhanced CT examination of the detection rate was 83.3%, higher than the B-ultrasound detection rate (52.6%). Unilateral parotid mass, CT enhanced detection rate of B-2 times. Conclusion Wassin’s tumor is the most common parotid MPT. Perfecting and enhancing CT examination can help to find MPT in the parotid gland before operation, so as to help determine the surgical plan.
