目的:探析胸腺上皮源性肿瘤的WHO组织学分型和CT征象的相关性。方法:选取某市区医院2014年5月至2015年5月期间收治并经病理检查证实的30例胸腺上皮源性肿瘤患者的资料作为研究对象,按照WHO组织学分型,将其分为六种类型。分属低危组,高危组,胸腺癌组,对三组患者的CT征象进行观察分析,探析WHO组织学分型与CT征象的相关性。结果:低危组20例,高危组7例,胸腺癌组3例;低危组患者的CT征象呈轮廓光滑,高危组呈轮廓不规则(P<0.05);高危组比低危组的肿瘤病灶内更易发生钙化,且浸润纵膈脂肪的发生率更大(P<0.05)。结论:按照WHO组织学分型,不同亚型的肿瘤其CT征象特点不同,低危组CT征象轮廓较为光滑,高危组与胸腺癌组CT征象轮廓较为不规则,且多发钙化,胸腺癌组易发生浸润脂肪和转移等。根据CT征象可判断WHO组织分型,有利于进一步诊断治疗。
Objective: To investigate the correlation between WHO histological classification and CT signs of thymus-derived tumors. Methods: The data of 30 patients with thymus-derived epithelial tumors who were admitted to the downtown area from May 2014 to May 2015 and confirmed by pathology were selected as research objects. According to WHO histological classification, they were divided into six types Types of. The patients were divided into low-risk group, high-risk group and thymoma group. The CT signs of three groups were observed and analyzed, and the correlation between WHO histological type and CT signs was analyzed. Results: There were 20 cases in the low-risk group, 7 cases in the high-risk group and 3 cases in the thymus cancer group. The CT signs of the low-risk group were smooth and high-risk group was irregular (P <0.05) The lesion is more prone to calcification, and the incidence of mediastinal infiltration fat greater (P <0.05). CONCLUSION: According to WHO histological classification, CT features of different subtypes of tumors are different. CT features of the low-risk group are smoother. CT features of the high-risk group and the thymus cancer group are more irregular, and multiple calcifications and thymoma are more likely to occur Infiltration of fat and transfer. According to CT signs can determine the WHO tissue typing, is conducive to further diagnosis and treatment.
