脾脏肿瘤与非肿瘤性病变的CT鉴别

Differentiation between tumorous and non-tumorous lesions in the spleen on computed tomography

目的:探讨脾脏肿瘤与非肿瘤性病变的CT表现及鉴别应用。方法:回顾性分析69例经临床确诊为脾脏病变的CT影像学资料,总结肿瘤性与非肿瘤性病灶影像特征及伴随征象,并采用卡方检验分析相关数据。结果:69例脾脏病变中,肿瘤性病变44例,边界不清者31.8%,出现包膜下积液者4.5%,出现腹膜增厚者2.3%;非肿瘤性病变25例,边界不清者56.0%,出现包膜下积液者60.0%,出现腹膜增厚者24.0%,脾脏肿瘤与非肿瘤性病变在三者的影像表现均有统计学差异(P<0.05)。结论:CT可较清晰地显示脾脏病灶,通过对病灶的边界及伴随征象的分析,有利于对脾脏肿瘤与非肿瘤性病变的鉴别。

Objective:To explore the manifestations of tumorous and non-tumorous lesions in the spleen on computed tomography(CT)and the application of CT in their differentiation. Methods:A retrospective analysis was carried out on the CT data of 69 patients diagnosed with splenic lesions;the imaging characteristics of tumorous and non-tumorous lesions and their accompanying signs were summarized;the chi-square test was used to analyze related data. Results:Among the 69 patients with splenic lesions,44 had tumor ous lesions,and 25 had non-tumorous lesions,with the percentages of patients with unclear boundary,subcapsular effusion,and peritoneal thickening to be 31.8%,4.5%,and 2.3%,respectively,in the former population,versus 56.0%,60.0%,and 24.0%,respectively,in the latter population;there were significant differences in the imaging findings of all three pathological changes between the patients with tumorous lesions and non-tumorous lesions(P<0.05). Conclusion:Splenic lesions can be clearly shown on CT. By analyzing the boundaries of lesions and accompanying signs,it is beneficial to differentiate tumorous lesions from non-tumorous lesions in the spleen.
